3.2 Theory / Construction of Contact Toner System ( KIP HDP )

3.2.1 General information on the process In the KIP2000 series printer a reverse development method is used, both development and cleaning process can be done at the same time. Fig. 1 shows “the configuration of no drum cleaner blade printing process”. The drum cleaner and the wasted toner bottle are not required, because the residual toner on drum surface after transfer process is returned to the Development unit during the development process. Fig. 2 shows “Simultaneous development and cleaning by the contact-type monocomponent non-magnetic development system”.

3.2.2 Print Process Step 1. Erasing process Drum surface charge is exposed by Eraser Lamp prior to 1st charging. Any residual charged potential on the drum surface is removed by this step. Any residual toner grains, not transferred on the previous drum rotation, are still on the surface of drum. The charge polarity of these toner grains can be both negative and positive toner particles. They are discharged to near 0 Volts under this process. (the small round spheres represent unused toner

on the drum surface.) Step 2. Charging process Drum surface is evenly charged by the negative 1st Charger (Primary). The residual toner is also charged by the 1st charger at this time, and all grains are the same negative polarity as the drum surface. Surface potential of Drum is determined by the potential of grid screen which is connected to ground through a zener diode in order to get a constant voltage. This voltage cannot be adjusted in the KIP 2000 Step 3. Exposure process With respects to the image’s data, infrared light from the LED head is exposed to the drum’s surface. The negative electrostatic charge on the drum is neutralized by this light, and surface potential decreases. As a result, electrostatic Latent Image is formed onto the drum’s surface. At this time, if there is any residual toner grains which may exist on the drum’s surface from the previous rotation, they will be no concerns with “shading effects” (blockage of LED head light by residual toner on the drum) by toner grains under the actual LED head exposure process. This is so due to the fact that the diameter of the toner grains are too small in diameter and they will not block the LED light.

Step 4. Simultaneous Development and Cleaning process Toner is always attracted to a more positive Voltage. The negative charged toner in the Contact Development Unit (see Vb, the Development Roller potential) are attracted to the higher potential, of an exposed area of the drum. (see figure 4, “Development” arrows) This will cause the toner to remain on these areas on the drum. Simultaneously, on unexposed areas ( no LED light ) the lower Potential, (see Vd) the residual toner is attracted to the development roller and therefore removed from the drum surface (removing unwanted toner from the drum or cleaning the drum) Step 5. Transfer process A positive corona is applied onto the media (from the back) and intern the media s charged positive. As a result, the more negative toner on the drum’s surface is transferred to the media. To prevent inefficient transfer and unwanted toner on the back of the media, the Media Guide Plate is grounded through a varistor. (NOTE) If the Guide Plate is grounded directly (shorted), the back side of paper is not charged and causes defective transfer. If the Guide Plate is floating (not shorted or not held at the varistor voltage), the Guide Plate may attract toner, thus causing unwanted toner (dirt) on the rear of media. Step 6. Separation process The media is charged positive by the transfer corona and is attracted to the drum’s surface by static electricity. An AC corona discharger removes the static electricity between drum and the media (paper). As a result the media is separated from drum. Step 7. Fusing process The media with the toner image is fed through the Pressure Free Fuser (Convection Heat Process) and the toner is fused to the media.

Fig.4-4-1 1. Summary

Image Charger (negative charge) is controlling a constant-current system, so that

the corona charging is not affected by environmental variations. Corona output is controlled ON or OFF by the signal HV_1ST from DC Controller. Then signal 1ST_LD is fed back from HVP.

2. Operation of HV1

If corona current flows more than adjusted value because of environmental variation, for example, feedback current level of current control circuit becomes higher. In this case, current control circuit works to Image charger drive circuit in order to decrease secondary current of high voltage transformer. Since primary voltage of high voltage power source is kept constantly at this time, primary feedback voltage is referred by voltage control circuit. Image charger drive circuit is controlled constantly in this manner.

Transfer Corona HV_TR(sig-in) TR_LD(sig-out)


Transfer Charger (positive charge) is controlled constant-current control system, so as corona charging effect is not affected by the environmental variation.

Corona output is controlled ON/OFF by the signal HV_TR from DC Controller. Then signal TR_LD is fed back from HVP.

2. Operation If corona current flows more than adjusted value because of environmental variation, for example, feedback current level of current control circuit becomes higher. In this case, current control circuit works to transfer charger drive circuit in order to decrease secondary current of high voltage transformer. Since primary voltage of high voltage power source is kept constantly at this time, primary feedback voltage is referred by voltage control circuit. Transfer charger drive circuit is controlled constantly like this way. The value of TR_ANLOG is controlling the output current of Transfer Corona. It is adjustable using Service mode 4-1d(Plain paper), 4-1E(Tracing Paper) and 4-1F(Film) respectively.

4.4.5 Charge Wire Cleaning Controller 1. Summary This machine auto-cleans the Charge wire. A cleaning pad moves one round trip along the charge wire via the Charger Wire Cleaning Motor(M4). 2. Operation Charger Wire Cleaning Motor works under the following condition ( when power is applied ). 1) When the Fuser temperature is 50degrees centigrade or less. When TH1 detected 50degrees centigrade or less, Charger Wire Cleaning Operation is done one round trip. Signals change as WCMTR=L, WCMTR_DIR=L, motor starts and Cleaning pad is send forward. When the Cleaning pad reaches to end of pass, WCMTR_OC (overload signal) is output. After WCMTR_OC is output for approx. 0.5 sec., WCMTR turns H and motor stops. For the next, signals change as WCMTR=L, WCMTR_DIR=H, motor starts reversibly. When the Cleaning pad reaches to end, WCMTR_OC is output for 0.5 sec., WCMTR turns H and motor stops. 2) In case the Fuser temperature exceeds 50degrees centigrade. When TH1 detected it exceeds 50degrees centigrade, Charge Wire Cleaning Operation is not done. However, in order to avoid Cleaning pad stays other end of pass, signals change as WCMTR=L, WCMTR_DIR=H, and motor starts reversibly. In case the Fuser temperature exceeds 50degrees centigrade, WCMTR_OC is output soon commonly and motor stops.

4.6 Down Sequence 4.6.1 Down Sequence caused by Low Fuser Temperature [℃] 210 200 TH2(Center) Controlled temperature It is switched is switched to 210 ℃ here. to 200 ℃ again. 180 TH3 150 130 110 Printing Printing stops here. restarts here. TH2 (Center) is controlling the temperature, while TH1 (Side) and TH3 (Bottom) are just confirming the temperature during normal opertaions.

While TH2 is controlling the temperature at around 200 degrees, the temperature around TH3 is around 180 degrees.

While continuous printing, temperature around TH3 decreases gradually.( lower plate ) When TH3 decreases less than 130 degrees, TH2 starts to control the temperature at 210 Degrees rather than 200. Down Sequence 1 If temperature around TH3 goes down and reaches 110 degrees, printing Is paused until it reaches up to 150 degrees. (It is approx. 90 secs, dependent on the wall voltage) Printing is paused during that period in order to help recover the temperature; it is called “Down Sequence”. Down Sequence 2 If TH2 detects 5 degrees less (adjustable with 4-2C) compare with 200 degrees during TH3 detects less than 130 degrees, this machine also enters to “Down Sequence”. Once “Down Sequence” is taken, Ready indication of Operation Panel starts blinking green, and it keeps blinking until the temperature of fuser is recovered.

4.6.2 Down Sequence caused by Toner Consumption Toner circulates as shown arrows. TLS1 TLS2 When TLS1 detects “L” status ( no toner ) for 15 seconds ( continuously ) toner is normally supplied for 2 minutes from Toner Hopper If TLS2 detects “L” ( no toner ) for 21 seconds continuously, the printing is paused for a few minutes after current printing is finished, in order to help supplying toner much more. However, if TLS2 detects “H” for 3 seconds, “Down Sequence” is cancelled at that moment. If Toner “Down Sequence” occurs, the Toner indication of Operation Panel starts blinking green, and it keeps blinking until the “Down Sequence” is complete.

(4) LED Head Strobe Time (Overall) (Sub Mode No.03) It is possible to change the LED Head strobe time ( on / off time ). This setting is the strobe time for all of 3 LED segments ( blocks ). The units are in “microseconds”, and the setting range is from 00 to 48. If you increase the value, the LED Head will produce more light and as the result image density becomes darker. Changes to this mode will be seen when producing test prints. Please note that the Scanner and Powerprint Controller send this density information to the printer, this adjustment alone will not usually correct density issues when copying or printing. Please produce test prints with the internal test patterns to set the printer density. Then confirm that the Scanner density values and Powerprint controller density values are set correctly before making any further adjustments to this sub mode.

(5) LED Head strobe time compensation (Left block) (Sub Mode No.04) It is possible to adjust the strobe time ( lighting time ) of LED Head left segment (block). This may be required to produce prints with even image density. ( see diagrams ) This setting is the compensation from the overall LED strobe time (Sub Mode No.03). When you select the value “35” on the Sub Mode No.03 and select the value “-05” in Sub Mode No.04, the strobe time of the left segment is “30 microseconds”. 35 ( value of No.03) - 5 ( value of No.04) = 30 (strobe time of left segment ) The units are in “microsecond”, and the range is from -10 to 10. If you increase the value, the left block of LED Head will increase in light volume. The result is the image density of left segment becomes darker.

(12) Fusing temperature cycle (Sub Mode No.0b) It is possible to adjust the low range of fusing temperature ( cycle or ripple). The setting unit is “degree centigrade”, and the setting range is from 0 to 30. Fusing temperature rises and falls within the specified range. The upper limit of range corresponds to the fusing temperature decided in each No.08, 09 and 0A. The lowest limit is decided by the following formula. Fusing temperature ( value of No.08, 09 and 0A) - value of No.0b = Lowest limit (Example) When the fusing temperature for plain paper is set to “175” in No.08 and the value of “No.0b” is “5”, the lowest limit of fuser temperature is 170 degrees. Temperature is controlled as follows. 1) When the fusing temperature rises up to the upper limit (175 degrees), the machine stops heating up the Fuser Element. - See (1) in the following figure. 2) Fusing temperature will drop during printing or during idle periods. - see (2) in the figure. 3) When the temperature falls down to the lowest limit (170 degrees), the machine starts heating the Fuser Element again. -see (3) in the figure. 4) the Fuser Element is heated up until its temperature reaches the upper limit. -see (4) in the figure. 5) The fusing temperature is kept within the 5 degrees range by repeating (1) to (4)

Note

THIS REQUIRES NO ADJUSTMENT FROM THE FACTORY SETTING! SEE YOUR DOOR LABEL.

If the range of temperature cycle is too small, this will cause the premature failure of SSRs.

(15) Fusing temperature overshoot (Sub Mode No.0E) When you turn on the printer, the Fuser can be heated past the point which is set in Sub Mode No.08, 09 and 0A. It is possible to specify how much the temperature should rise past that set in “Fuser Temperature “ during the warm up period. The units are in “degree centigrade”, and the setting range is from 0 to 40. Supposing the fusing temperature decided in No.08 is 175 degrees centigrade and you select “10” as the overshoot, the Fuser is heated up to 185 degrees centigrade during the warm up time. 175 (Fusing temperature decided in No.08) + 10 (Setting value of No.0E) = 185 There should be no reason to adjust from the factory setting other than poor fusing on “first copy out”. This will allow all the internal fuser components to ensure they reach the correct temperture before printing commences.

Please do not adjust from factory default ( see door label )

(16) Transfer Corona ON timing (Sub Mode No.0F) It is possible to adjust the on timing of the Transfer Corona. The unit is “mm”, and the range is from 001 to 100. If you increase the value, the on time of the Transfer Corona is delayed during the print process. This will cause a greater amount of the leading edge image ( toner ) not to be transferred onto the paper. It will remain on the Drum. As the result of it, the print will have a wider margin region on its leading edge. Turned on too late =

the leading edge image may be seen faintly on the print, this can poor image on the leading edge and cause repeat of the lead edge further down the print

Turned on too early = unwanted toner pulled from the drum / dev unit which may cause the printer to become dirty very quickly, usually seen as toner on back of page and dirty corona wires

(Increasing the value by “1”, the void gets 1mm longer.)

If you decrease the value, the Transfer Corona turns off earlier. As a result a greater amount of trailing image (toner) is not transferred to the paper. It remains on the Drum. This will cause the print to have a has a longer image void on the trailing edge. (Decreasing the value by “1”, and the void becomes 1mm longer.) Turned off too early =

the trail edge image may be seen faintly on the print, this can poor image on the tariling edge and cause repeat of the trail edge image on the next page

(20) Cut length (Copies Buffered from Scanner, Standard Cut or Prints from Controller)

(Sub Mode No.13) It is possible to adjust the cut length in this Sub Mode noting the following : Copies from the K-75 Scanner: A: When the speed of the Scanner and Printer matches ( K-66 with a 2050 Scanner, 50mm / sec )

(21) Cut length ( Copies from Scanner Syncro Cut , first copy out ) (Sub Mode No.14)

It is possible to adjust the cut length in this Sub Mode noting: Copies from the K-75 Scanner: A: When the speed of the Scanner and Printer matches ( K-66 with a 2050 Scanner, 50mm / sec )

- when using “Synchro Cut” only the first copy out uses this sub mode, every other copy uses cut length in 4 - 13.

e.g. when you have one orginal and have selected five copies to print, the first print uses this cut signal. Prints 2 to 5 use the signal in 4-13 ( any image that is not buffered before printing uses this cut signal )

B: When the speed of the Scanner and Printer does not match, ( K-66 with 2080, 2120 etc ) - do not use this mode ( as all images are buffered before spooled to the printer)

Prints from the Controller Does not use this mode ( see 4 –13 ) You can specify the cut length for each roll media sizes. The setting unit is “mm”, and the setting range is from 01 to 20. If you increase the value, the cut length is extended. As the result, the “white” region at the trailing edge becomes longer, page size increases. [Operation] 1) Select the Sub Mode Number “14”.

(22) Image Void – Trail Edge (Copies Buffered from Scanner, Standard Cut or Prints from Controller)

(Sub Mode No.15)

It is possible to adjust the end of the print image ( closing the image data bus or end of the image ) in this Sub Mode noting: Copies from the K-75 Scanner: A: When the speed of the Scanner and Printer matches ( K-66 with a 2050 Scanner, 50mm / sec )

- when using “Standard Cut” - when using “Synchro Cut” every copy, but the first copy. e.g. when you have one orginal and have selected five copies to print, the first copy does not use this image bus sub-mode ( see 4 - 16 ); copy numbers 2 to 5 uses this data bus closure information! ( any image that is buffered in the scanner before printing uses this signal )

B: When the speed of the Scanner and Printer does not match, ( K-66 with 2080, 2120 etc ) - when using “Standard Cut” - when using “Synchro Cut” every copy printed e.g. when you have one orginal and have selected five copies to print, all prints use this sub-mode! ( any image that is buffered before printing uses this data bus closure signal, when the speed does not match all images are buffered then spooled to the printer )

Prints from the Controller All prints from Powerprint use this data bus closure signal You can adjust the closure of the bus for each roll media size. The units are in “mm”, and the range is from 00 to 20. If you increase the value, the image bus will be closed earlier, therefore removing image from the trailing edge of the print. As the result, the “white” region at the trailing edge becomes larger ( page size remains the same.)

(23) Image Void – Trailing Edge ( Copies from Scanner Syncro Cut , first copy out ) (Sub Mode No.16)

It is possible to adjust the trailing edge image in this Sub Mode noting: Copies from the K-75 Scanner: A: When the speed of the Scanner and Printer matches ( K-66 with a 2050 Scanner, 50mm / sec )

- when using “Synchro Cut” only the first copy out uses this sub mode, every other copy uses cut length in 4 - 15.

e.g. when you have one orginal and have selected five copies to print, the first print uses this image signal. Prints 2 to 5 use the signal in 4-15 ( any image that is not buffered before printing uses this image void signal )

B: When the speed of the Scanner and Printer does not match, ( K-66 with 2080, 2120 etc ) - do not use this mode ( as all images are buffered before spooled to the printer)

Prints from the Controller Does not use this mode ( see 4 –15 ) The unit is “mm”, and the setting range is from 001 to 300. If you decrease the setting value, the image bus will be shut down earlier. As a result , more trailing image will be deleted from the print. Note: Trailing Image area is finished with earlier timing either Sub-Mode 15 or 16. Please use the correct Sub Mode to adjust the trail edge image.

(41) AC Corona OFF Timing (Film) (Sub Mode No.28) It is possible to adjust the timing of AC Corona OFF after the trailing edge of the paper passes the position of Paper Entry Sensor(PH5). This setting is effective when you take a print using a Film. The setting unit is “mm”, and the setting range is from “00” to “99”. When the value is selected at “00”, the function of AC Corona OFF Timing turns invalid. (AC Corona is always applied during the interval of continuous print.) If you decrease the setting value smaller than “60”, AC Corona turns OFF earlier than the trailing edge of the paper. Increase the setting value pressing the SW724, and decrease it pressing the SW725. (Present setting value is “60”. Increase the value to “70” pressing SW724.) (Decrease the value to “50” pressing SW725.)

(45) Down Sequence Temperature adjustment (Sub Mode No.2C) It is possible to adjust the temperature to enter in Down Sequence 2. As it is explained on page 4-20, Down Sequence 2 means: “If TH2 detects “certain” degree lower compare with 200 degrees during TH3 detects less than 130 degrees, this machine enters to “Down Sequence”. This “certain” degree is adjusted in this sub-mode. The setting unit is “degree”, and the setting range is from 05 to 15. If you increase the setting value, this machine does not enter to the “Down Sequence” so easily. Instead, you should be careful that “non-fused” might happen.

8.7 Error Reset / Error Mask Mode

8.7.1 Function It is possible to make the machine ignore error code by masking such errors in this mode. Each error is shown by the Mask Code. The following list shows each Mask Code and its target to mask (Name of error and Error Code).

Mask Code Name of error Error Code 00 Fuser Temperature Rising Error E-01

01 Fuser Over Temperature Error E-02 02 Developer Error E-04 03 Cutter Error E-07 04 Counter Error E-06 05 Fuser Thermostat Error E-21 06 Tray Error E-22 07 Wire Cleaning Error E-16 08 Fuser Agitator Fan Error E-28 10 Roll Deck Jam J-01

Notes (1) When “Fuser Temperature Rising Error (E-01)” or “Fuser Over Temperature Error (E-02)” occurs during the usage of machine, it is impossible to clear the error even if you turn off the machine after taking a proper treatment because it is memorized in the memory. When these errors occur, do as follows. 1. Find the cause of error and take a proper treatment. 2. Turn on the machine. The same Error Code will be indicated again as “E-01”. Enter the Service Mode, and then select the Error Check Masking Mode. 3. Mask the error in the way mentioned on and after the next page. The error will be cleared. 4. Do not forget to cancel error masking after clearing the error because it is very dangerous if the machine ignores those errors. (Error masking will be cancelled automatically if you turn off the machine or cancel the Service Mode.) (2) It is impossible to mask the Door Open Error.
