Loading mediaYou can use either roll or single sheet media. To ensure straight paper loadingand avoid skewing, be sure to hold the media parallel to the platen. Use the loadlines on the platen as a guide to correctly align the media. Be sure to load fromthe back only. Set the media guides to the width of the media.

! IMPORTANT! It is very important to use only ENCAD QIS media with yourprinter. Some third party media has been found to generate electrostatic dis-charge in excess of 20 KV. Emissions of this level can cause arcing between thelower roller and printer leg. These conditions can be temporary or permanent.

! Depending on the model, the printer can use media up to 60" wide. The rolls canbe heavy, so you may want to have someone help you to load them.

! If your roll media has wrinkled or damaged edges, cut off the damaged part ofthe roll prior to loading to prevent the media from jamming in the printer.

➪➪➪➪➪ To load roll media on the NovaJet 7361 Mount the roll media on the back of the printer, orienting it as shown

in the following illustration. Slide the roll holders into the media core,and tighten the thumbscrews on the roll holders to secure the roll.

Note: The NovaJet 505 does not have the takeup roller as shown in the preced-ing illustration The 505 has clips on the platen that are designed to hold media inplace while printing. Slide the left clip to adjust for different media sizes. Theclips were specifically designed for bond media and may not be useful with othermedias. If you don't need the clips, they will slide to the side away from themedia.

Using the second feed rollThe second feed roll option is not available to you if you didn't order the optionaltakeup and dryer system. The optional takeup roll can also be used as a feedroll. If you use the optional takeup roll as a feed roll, you cannot use the takeupsystem. If you want to use the optional takeup roll as a feed roll, set the printer toROLL2 by pressing Setup Menu/Paper Options Menu/Supply Type/Roll2.Follow the loading instructions in the previous section using the bottom roll.

Using the optional takeup rollThe optional takeup roll allows unattended printing by automatically windingprinted media onto a core. In this mode, the automatic cutter is disabled. Whenusing this option, be sure that the media sensor on the printer's right leg is notblocked.Depending on the ambient humidity, temperature, and amount of ink coverage,you may want to turn on the dryer and/or set a dry time as described in theReference Guide on the system CD-ROM. If you are using the dryer, position itso that the fans blow on the media.

➪➪➪➪➪ To use the takeup roll1 Set the printer to Takeup mode by pressing Setup Menu/Paper

Options Menu, Supply Type/Takeup, then press OK. This enablesthe takeup roll and disables the cutter.

2 Install an empty core onto the takeup guides. Be sure that the corewidth matches the width of the media you are using.

3 Slide the roll guide into the media core, and secure it by tighteningthe locking mechanism.

Since media cores can be shorter than the width of the media,position the media guide 1/8” from the end of the core and lock it intoplace.

Using at least three pieces of tape, attach the leading edge of themedia to the takeup roll at the left, right, and center of the core.As printing progresses, the media is looped down in front of thetakeup core until it is detected by the sensor on the printer leg. Thetakeup roll is then activated to roll the media.Be sure not to block the sensor!

Note: If you are running narrow media, and depending on ambienttemperature and humidity, you may want to set a dry time and/or turn onthe dryer as described in the Reference Guide on the system CD-ROM, ifyou are running a long plot. Because of the print speed and the narrowmedia, the ink may otherwise not have sufficient time to dry before themedia is rolled onto the takeup core.

➪➪➪➪➪ To unload the takeup roll1 Press the Cut button to cut the media.2 Roll the printed or unused media onto the takeup.3 Slide the media and core out of the printer.4 Release the adjustable roll guide.

➪➪➪➪➪ To load sheet media 1 Press Setup Menu/Paper Options Menu/Supply Type/Sheet.

Then press OK.2 Load the sheet from the back of the printer, aligning it with the

alignment mark on the platen.3 Make sure that the media is flat and under the rollers. After a few

seconds, the printer will automatically sense the media's presenceand load it until it reaches the start position on the platen.

Note: On the NovaJet 736, make sure the roll guides are moved out ofthe paper path. If not, the paper entering the printer could hit the rollguides and could cause skewing.Caution: When using Expanded Margins, cut sheets may fall from theprinter at the end of the print. To avoid this, use Normal Margins for cutsheet media.

Moving the carriageWhen not in use, the ink cartridges rest in the service station at the right side ofthe printer. This device seals the inkjets to prevent them from drying out. Withthe power turned on, select Utility Menu/Access Cartridge on the controlpanel to move the carriage away from the service station so that you can install,change, adjust or clean the ink cartridges, change the cutter, or clean the servicestation. Caution: Do not move the carriage manually as you could damagethe printer.

Installing the cutterA cutter located in the ink cartridge carriage cuts roll media. The printer isshipped with the cutter installed.

! Be careful when handling the cutter to avoid injury.! Cutting media with a worn cutter can cause the media to jam and create

a ragged cut line. Replace the cutter to avoid this condition. Do not cutmedia on the printer with an external knife, as you could seriously dam-age the platen and void the warranty.

➪➪➪➪➪ To install the cutter1 Press Utility Menu/Access Cartridge button to move the carriage

out from the service station.2 The cutter fits in the printer on the left side of the carriage. To remove

an older cutter, push the cutter lever down and pull it out. Install thenew cutter by pushing it into the slot until it clicks into place.

3 Press Utility Menu/Access Cartridge to move the carriage backinto the service station. This ensures that the cutter blade is in thehome position.


20

Filling the ink reservoirsThe printer can support long, uninterrupted printing runs because of the largecapacity of each of the four ink reservoirs. The ink reservoirs are located in theprinter's left side cover.Note: On the NovaJet 700, do not add more than 300ml of ink or fill higher than1 inch from top of the reservoir when running at carriage speeds faster than 5.The NovaJet 750 reservoirs can be filled to the top.Note: Refill reservoirs when the ink level is approximately 50ml or 1/4 inch fromthe bottom. Allowing ink levels to drop lower increases the risk of getting air inthe ink lines and losing pressure.Note: The left side of the NovaJet 750 will look different than the followingillustration. The NovaJet 750 has eight reservoirs in an open bay. The left fourreservoirs are attached to the grey lines. The bay under each of the left fourreservoirs is numbered 4, 3, 2, 1: 4 = Yellow (Y), 3 = Magenta (M), 2 = Cyan(C), 1 = Black (K).

5 Press the button on the ink primer to activate the vacuum and drawink from the reservoir into the needle.

6 When ink is visible in the ink primer sight tube (should take 5-10seconds), close the ink delivery lines by pushing valve up andremove the cartridge needle from the ink primer. Note: When youremove the ink primer from the ink delivery lines, continue pressingbutton a few seconds to prevent leaking from the ink primer.

7 Insert the cartridge needle into the hole in the top of the ink cartridge.Be sure the needle is tightly connected by turning the fittingclockwise until finger-tight.

8 Gently tighten the fitting (about 1/4 turn) to prevent air leaks. Do notovertighten. Open the ink delivery lines by pushing the valve down.

9 Wait 20 seconds for the ink pressure to stabilize. Remove thecartridge from the carriage and remove the blue tape from the jetarea of the cartridge. CAUTION! Do not tilt the cartridge uphigher than a 30 degree angle. This could cause the cartridgeto lose pressure.


34

Check for ink on the jet plate. Continuous bleeding of the jet plateindicates a loss of vacuum in the cartridge or an air leak in the lines.A small amount of ink can be cleaned off the jet plate by dabbing witha moist, lint-free cloth.


11 Repeat for each cartridge.12 Press Utility Menu/Access Cartridge to return the carriage to the

service station.13 Print the color test, prime test pattern and paper axis test as

described later in this guide.14 If all colors look fine, go on to step 18. If any color drops out, prime

cartridges as necessary, using the ink primer. Place the suction endof the ink primer over the jet area of the cartridge.

15 Make sure the ink primer is making good contact with the jet area.Pulse the pump 3 - 5 times, until the ink is visible in the ink primersight tube. Maintain good contact between the inkjet plate and thepump for an additional 5 seconds.When removing the ink primer, use the silicone tip to wipe and cleanthe jet plate. Remember to clean the silicone tip of ink before movingto the next cartridge. Note: When you remove the ink primer fromthe cartrodge, continue pressing button a few seconds to preventleaking from the ink primer.

16 Reprint the color test and prime test pattern. (The paper axis test isonly required when changing media). Inspect to ensure properpressure is maintained for each color.

17 Re-prime cartridges as necessary to remove clogs. Manuallybypass (compensate) clogged jets as necessary. Manualcompensation is described later in this guide.

18 Once all cartridges are working correctly, print the color deadbandand color calibration test patterns as described in the section onAligning the ink cartridges which follows.

Printing the color testPrinting the color test verifies a proper manual prime and that pressure is setproperly.

➪➪➪➪➪ To print the color test1 Be sure media is loaded in the printer.2 Select Utility Menu/Service Menu/Diagnostics/Color Test.3 Change the color test percentage to 100% and press OK.

The test prints.4 Verify that all bands print a solid pattern. This indicates that the

cartridges were properly primed. If it doesn't print a solid pattern, runthe color test again.

Printing the prime patternBefore printing and during printing, the printer wipes the ink cartridge jets at theservice station. This function is user selectable during printing or between prints.Still, ink cartridge jets can become clogged, especially with prolonged exposure tothe air or with nonuse. Printing the Prime pattern helps to clear the jets and tocheck that the ink cartridges fire properly. We recommend that you print the primpattern daily to ensure the best possible print quality.The printer includes a feature called Open Jet Detection and Compensation. Thisfeature helps maintain optimal print quality and gives you the confidence to printlong, unattended jobs. During multi-pass printing, the printer will automaticallycompensate for jets found to be electrically damaged. The only interventionneeded is to verify that there are no clogged jets and then choose which printmode is most appropriate for your needs. This is done by printing the Prime testpattern and then setting the print mode accordingly.

➪➪➪➪➪ To print the prime pattern1 With media loaded, press Utility Menu/Prime.

A test pattern prints. It should be smooth with no obvious banding.2 If the printed results are unsatisfactory, run the test several more

times to unclog the inkjet nozzles.

➪➪➪➪➪ To interpret the Prime test patternThe test pattern consists of bands of color for each cartridge and asloping line. Within the Prime test pattern, each jet is representedwith a short horizontal line. Together, these short horizontal linesform a “stair step” pattern. Clogged jets appear as missing ormisdirected lines in the “stair step” pattern. Electrically defective jetsappear as solid bars. Electrically defective jets can be automaticallycompensated in certain modes. The print modes for whichcompensation is available are shown clearly above the Prime.

A solid bar indicates anelectrically defective jet. Jet Compensationwill automaticallycompensate for thatjet.

A missing line or "gap",misdirected line, or a light-printing lineindicates a clogged jet.

The CMYK header lets youknow the availableprintmodes that will providecompensation.

Clogged jetsClogged jets cannot be automatically detected and therefore must be clearedmanually. If a jet is clogged, it will appear in the prime pattern as a gap in thesloping line for each cartridge.To clear a clogged jet, clean and prime the affected cartridge according to theMaintenance Guide on your system CD-ROM. Your goal is to eliminate all gapsin the “stair step” pattern before starting your job.

Aligning the ink cartridgesTwo tests are provided to help you align the cartridges: Color Deadband Com-pensation and Color Calibration. Note: Color Deadband Compensation isused on 630/700 series printer only.Color Deadband Compensation provides a method for adjusting dot placement.In bidirectional printing mode, the velocity of the carriage causes dots to miss thetarget area on the media. The color deadband test pattern lets you check thevelocity deadband values and adjust them for the best printing results. A loupe isprovided in the accessory box to help you check the prints.

Color calibration aligns the inkjets of the cartridges to each other. Misalignmentcan result from small tolerance variations in cartridges during manufacturing andfrom cartridge alignment in the printer. Color test patterns let you check thehorizontal and vertical alignment values and adjust them for the best printingresults. A loupe is provided in the accessory box to help you check the prints.You should perform Color Deadband Compensation before performing ColorCalibration. Perform Color Deadband Calibration and Color Calibration eachtime a cartridge is replaced with a different cartridge. If you remove andreinstall the same cartridge, only Color Calibration needs to be performed.

Paper axis calibrationChoosing Utility Menu/Calibration Menu/Paper Axis Test lets the printerdraw a set of vertical marks to calibrate the paper axis. To measure the markslaid down by the printer, you will need a ruler or scale at least 33 inches (838.2mm) long. (CD#2 of the NovaJet System CD set contains a ruler file than can beprinted on your printer.) The vertical marks should be exactly 33.00 inches(838.2 mm) apart. If the distance between the marks is different from thatshown on the display, you may adjust the printer by setting its values to match thelength or width you measured. Note: The Paper Axis Test should beperformed every time new media is loaded.

➪➪➪➪➪ To print the Paper Axis calibration test pattern1 Load the printer with media that is at least 36 inches (91 cm) long.

Use the media that you are planning to use for printing.2 Press Utility Menu/Calibration Menu/Paper Axis Test. The printer

prints two marks.3 Remove the media from the printer and measure the distance

between the marks. If you need accurate printing (e.g. registeringmultiple panels or "tiles"), you must use a very accurate measuringdevice. We recommend a steel rule at least 36 inches (91 cm) longwith calibration marks every .01 inches ( 0.254 mm). The distancebetween the marks should be exactly 33.00 inches (838.2 mm).

4 If the measurement is not exactly 33.00 inches (838.2 mm), selectPaper Axis and adjust the value to the measurement read on thesteel rule. (e.g. If you read 33.02 on the rule, enter this value in theprinter. It becomes a calibration constant.)

5 Repeat steps 2-4, this time the measurement should be 33.00inches (838.2 mm).

6 Press Utility Menu/Calibration Menu/Use Calib XY and selectON.

Cartridge recognitionThe printer is designed to use only cartridges specific to your printer model. Toeliminate potential damage to the printer, a Cartridge Recognition feature checksto ensure that the proper cartridges are installed, and that they are installedproperly. Cartridge recognition is performed when a print request is received(i.e., image data, prime, etc.).

In addition to cartridge recognition, the printer automatically performs tests on thecartridges and uses the information to improve image quality, monitor cartridgelife, and update the user with system status. Some tests are performed betweenprints and require no user input, while others require user input.Cartridge-related error messages are listed in Appendix E of the ReferenceGuide on the system CD-ROM.To clear a cartridge-related error, press Utility Menu/Access Cartridge tomove the carriage to the position which allows replacement of the ink cartridges.Check to make sure you have the proper cartridges installed in each position, thatthey all contain the same type of ink (i.e. GX, GS Plus, or GO) and all cartridgesare installed properly. Install new cartridges if necessary.

➪➪➪➪➪ To clear cartridge recognition error:1 Press Utility Menu/Access Cartridge to move the carriage to the

position which allows replacement of the ink cartridges.2 Verify that four valid cartridges are installed. Replace any invalid

cartridges.3 Press OK. If the problem has been corrected, the printer will

proceed with the print request. If the problem has not beencorrected, the printer will beep.

Pausing the printerTo pause the printer while printing, press the Pause button. Press it again toresume printing.

Canceling a printTo cancel a print, first send a cancel order from the computer using the appropri-ate command for your software application. For example, you can delete the filein the Print Manager/Print Options. To clear the buffer after cancelling a print,press Reset on the Main menu.
