The system has not been designed to be used in presence of vapours, anaesthetic mixtures that are flammable with air, or oxigen or nitrous oxide. Ensure that water or other liquids do not get into the machine so as to prevent short-circuits and corrosion. Always disconnect from mains before cleaning the machine. Where necessary, accessories such as lead-sealed aprons must be used to protect the patient from radiations. Only the patient and the operator may remain in the room during the execution of the radiography examination. I-MAX EASY has been developed for continuous use with intermittent load. The prescribed operating cycles to allow the heat accumulated by the radiogenic source to be discharged must be observed. Although the appliance has been designed to have a reasonable degree of protection from electromagnetic interference, it must be installed at a certain distance from electricity transformer rooms, static continuity unit, portable two-way hand radios and cellular phones. The latter may only be used at a distance of over 1.5 meters from all elements of the machine. All instruments or equipment for professional use and used near the machine must be in conformance to the electromagnetic compatibility standards. Nonconforming instruments whose low immunity to electromagnetic fields is known must be installed at least 3 meters away from the I-MAX EASY and be powered via an independent electric line. I-MAX EASY must be switched off during the entire period of use of ESU (Electro Surgery Units) units or similar equipment. Clean or eventually disinfect the chin support, positioning handles, temples clamp support, nose rest and any other part that may come in touch with the patient. At the end of the examination, replace the bite and the ear rods.

Although the X-ray dosage supplied by dental radiology appliances is on average low and distributed over a relatively small surface, the operator must take the necessary precautions and/or follow the safety procedures for both himself and the patient during an exposure. We recommend that the X-ray activation always be commanded from an X-ray protected area via remote control. If it is necessary to operate the exposure near the patient, remain at the maximum distance allowed by the remote control cable in the direction opposite to the emission of the X-rays, at a distance of at least 6.6 feet (2 meters) from both the radiation source and patient.

3.23.23.23.2 DescrDescrDescrDescriptioniptioniptioniption
I-MAX EASY has been designed to perform the following examinations:
• Panoramic examination
• "SINUS" examination of the paranasal sinus
• Examination of the Temporo-Mandibular Joints (TMJ) with open or closed mouth on a single image
All the allowed examination may be made with different parameters according to the setting of the remote-control (please refer to chapter 6 of User’s Manual).
I-MAX EASY is controlled by a soft touch console and equipped with an alphanumeric digital display for a clear indication of the working parameters and operative messages. The operative cycle is entirely run by a microprocessor, controlling its different modes : from programming of the emission parameters according to the chosen examination and the patient's size, to the voltage fluctuation and to the notification of possible anomalies, failures or errors.
The excellent quality radiographs thus obtained is the result of a clever design based upon the pseudo-elliptic rotation system, the original light beam-luminous cross pattern centering system, the use of green emitting Rare Earth Intensifying screens and most of all the small dimension of the focal spot. This particular rotation system allows an orthogonal imaging of all teeth and wide image layer with an optimum focused zone of 10 mm for the incisors and 20 mm for the molars.
I-MAX EASY, besides operating in the programmed mode, can also operate in the manual personalized mode by modification of the parameters, as described in chapter 5.
In the Panoramic and TMJ modes, with all interlock enabled, it is possible to activate the TEST push button 31 (see Figure 7-7 at the end of the manual).
The TEST functioning mode allows the operator to check the functionality of the selected examination cycle or to show to the patient the examination he will undergo (including all movements of the machine) without emitting X-rays.
The TEST push button as X-ray button is a "dead man" button, which means thus if it is released during the examination cycle, the latter is interrupted stopping the movements in progress. To re-start the cycle first reset the unit by means of the key 32 (Figure 7-7), than start again the function which was interrupted.

kVp The peak tube potential is directly measured with a non invasive
kVp-meter, accuracy ±3kVp. When performing the measurement, make sure that measuring probe is completely covered by the X-ray beam. A direct measurement of the high voltage can only be carried out by specialized technicians in a suitable testing laboratory as it requires disassembling of the tubehead.
mA The output current is determined by measuring the voltage drop on a
resistor (1kΩ, 5%) using a digital multimeter, connected to the corresponding plugs, as indicated on paragraph 7.4 (digital multimeter set to VDC 20V, 1V=1mA).
t The exposure times are determined by using a timer/counter, having an
accuracy of 0.1%, measuring the duration of part of the voltage applied to the primary side of the tubehead, during the exposure phase.

WARNING: The following test implies X-ray emission; please follow all measures envisaged by local safety regulations. The system is qualified to operate with a maximum line voltage regulation of 3% at 108V, which is the line voltage generating the highest current draw from the line. Check of line regulation: a proper installation has to make sure that the line provided in the facility where the device is being installed, meets the requirement of line voltage regulation. In order to carry out this test proceed as follows:
1. Using a true RMS Voltmeter asses the line voltage value under no load condition (Vn).
2. Select a timer setting of 2 seconds and make an exposure.
3. Using the same RMS Voltmeter, read the line voltage during exposure which is the under load condition (Vi).
4. Calculate line voltage regulation as: ((Vn-Vi)/Vi)x100. To make absolutely sure that the line meets the requirement independently from possible drift of the line voltage during life of the equipment the measured line voltage regulation must be smaller than 2.4%.
5. In case line voltage regulation does not meet the spec, refer to paragraph 5.1 of this manual and consult with a certified electrician or the local Power Company.

The S5 function allows to change the default angles and times for any function and size. In particular, you can change the X-ray emission start (A2) or end (A5) angles, the deceleration (A3) or acceleration (A4) ramp start angles or the duration of the four TMJ exposures by simply using the procedure here after described for the parameters you want to change. For all the following procedures hereafter described, entering the set-up program is required (see paragraph 7.2), then press "s" (39) followed by "T" (31) several times until the function "S5 ......" is displayed and press "s" key to set "S5 ON" (see paragraph 7.2.2, function "S5" for further details). NOTE: Press "R" (32) to exit the S5 function. This will not set automatically function S5 to OFF (S5 OFF) and after an exposure the string "T1 020" will be displayed. To access the normal working function again, return to the set-up program and change S5 to OFF. NOTE: Every change must be carried out by pressing the "increase" (41) and "decrease" (40) keys.

This message can be displayed on two different conditions, due to a fault of the potentiometer used to control angular position of the rotating arm. This message can be caused by a failure of the potentiometer or a bad contact in the connection between the potentiometer and the control circuit (see chapter 9 – General diagram code 39099327 – Page 4 of 5). Another possible cause is the failure of one of the start/stop rotation microswitch S2/S3 (see Figure 7-5). Check the microswitch and/or connections.

The procedure here after described, allows to store into the system non-volatile memory the resistance values of the potentiometer (then converted by the A to D Converter) when the tube-head is in the starting position (0°) and final position (245°). In this way, the system can continuously detect the angular position of the arm by reading the value of the potentiometer attached to the mechanics. NOTE 1: The following procedure must be started with the machine OFF and cable X1 disconnected. NOTE 2: The following procedures requires to access the set-up programs; access to the programs is achieved as follows:
a while holding the "s" (39) button depressed, turn the unit ON and do not let go until the unit has gone through its check out mode which will be signalled by 2 distinct sounds, one short and one long; thereafter, the display would be blank
b press keys 37, 34, 29 in sequence (small, child, TMJ1 buttons); the display will remain still blank
c Now the following keys, with the relevant functions, are active:
• "s" (39) to change the value of the "software DIP-switches" (S0 to SB)
• "R" (32) to restore the default parameters of the non-volatile memory
• "T" (31) to calibrate the circuit associated to the potentiometer of the rotating arm.
Selection of the desired option is described within the procedure. 1. With the unit OFF, loosen the clutch of the belt motor.
2. Manually move gently the rotating arm to the 0° position, until reaching the relevant microswitch S2 (see Figure 7-5).
3. Check the value of the new potentiometer to install (5kΩ, 10kΩ or

NOTE: During the replacement of the start/stop microswitch, remove only the defective microswitch (without the fixing plate), in order to position the new one in the same position of the defective one and avoid to restore the angles parameters. The procedure here after described, allows to replace one of the microswitches used as rotation start / stop references. 1. After having gained access to the rotation group, remove the failed
component and place the new microswitch.
2. Using a DVM in V reading, full scale 10V, position its terminal between pins 2 and 3 (see next Figure) of the rotation potmeter R2.
3. Turn ON the device and wait for the end of the initial self-test.
4. If the replaced micro is the START micro, go to the next step; if the replaced micro is the STOP micro go to step 11.
5. Press "R" key (32; Reset); the arm will rotate up to reach the 0° position.
6. Read the value of the potmeter voltage on the DVM: if the value is between 160mV and 180mV the position of the micro is already correct and proceed to step 16; if it is outside the range move to next step.
7. Press "T" key to move away the arm of an angle between 45° and 90°.
8. If the reading of the potmeter voltage of step 7 was below the lower limit of the range, move the microswitch so that the arm will reach it earlier than in the previous position; on the contrary if the reading of the potmeter voltage of step 7 was over the upper limit of the range, move the microswitch so that the arm will reach it later than in the previous position. To move the microswitch release the plate supporting it and adjust its position.
9. This procedure is a trial and error process: repeat steps 6 to 9 until the reading of the potmeter voltage with the arm in 0° position is between 160mV and 180mV.

11. Read the value of the potmeter voltage on the DVM: if the value is between 2.00V and 2.30V the position of the micro is already correct and proceed to step 16; if it is outside the range move to next step.
12. Press "R" key (32; Reset) to move away the arm which will go back to 0° position
13. If the reading of the potmeter voltage of step 12 was below the lower limit of the range, move the microswitch so that the arm will reach it later than in the previous position; on the contrary if the reading of the potmeter voltage of step 12 was over the upper limit of the range, move the microswitch so that the arm will reach it earlier than in the previous position. To move the microswitch release the plate supporting it and adjust its position.
14. This procedure is a trial and error process: repeat steps 11 to 14 until the reading of the potmeter voltage with the arm in 245° (STOP) position is between 2.00V to 2.30V.
NOTE: After the above mentioned test, it is suggested to verify and store the start/stop angles following the procedure described at paragraph 7.9.1, steps from 8 to 23. 15. Run the procedure to verify centering and symmetry of the
panoramic, making an exposure on the round centering tool as described in paragraph 7.7.4.
16. On the basis of the values determined for the PAN adult (A2, A3, A4, A5) set the value of the angles A2 and A5 for child as follows:
− A2 child = A2 adult +9°
− A5 child = A5 adult -9°

Arm rotation speed is very critical and affects the quality of the image. If either the arm rotation motor or the Power Board A1 is replaced, it’s important to implement the procedure listed below and at the end to verify the success of the intervention checking image symmetry as described in paragraph 7.7.4. 1. Disconnect power line from the unit.
2. Remove the cover of the electronics cabinet and disconnect connector X9 on the Power board A1.
3. Switch ON the unit.
4. Switch ON the PC, access QuickVision program, connect to panoramic unit, wait until the sensor is ready for acquisition (green led sensor ready ON). To speed-up the operation, after each exposure, turn OFF and ON again the unit.
5. Make an exposure in adult panoramic and check that the exposure time shown on the display of the hand control at the end of exposure (keep pressed the X-ray button) is in the range 16.8 e 17.2 sec.; repeat this test three times and check the time displayed on the hand control.
6. If the exposure time is not correct, verify on the CPU board, that the jumper X22 (position 5-6) and the both flat cable X16 and X17 are well inserted (see chapter 9 - drawing 7).
7. If the problem is still present, using a digital multimeter set to VDC, measure, during arm rotation, the voltage on A1 Power board between resistor R54 (side close to component N1) and TP2 (GND) (see chapter 9 - drawing 3). If the value (typically it is 300mV) is higher than 400mV for both the speeds, it is necessary to replace the motor (code 6608318900).
8. Turn OFF the unit and, using a digital multimeter set to ohm, place on A1 Power board (see chapter 9 - drawing 3) the positive terminal on capacitor C18 (towards the outside of the board) and the negative terminal on the anode of V23 (towards the outside of the board) located near the trimmer R45. Before starting the measure, wait for one minute to allow the capacitors to discharge.
9. Calibrate trimmer R45 (Ramp) to read a value in the range 155 – 165 kohm.
10. Remove jumper X22 pin 5-6 on the CPU board A2 (see chapter 9 - drawing 7). Turn ON the unit and make an adult panoramic exposure: exposure time read on the display of the hand control at
the end of exposure must be 15.3 sec. ± 0.1 sec. If different act on trimmer R39 (Speed 1) located on power board A1 (turning clockwise time becomes shorter) until the correct value is obtained.

11. Place jumper X22 on pin 4-5 (red H4 on Power Board A1 must turn ON) and make an exposure; exposure time read on the display of the
hand control at the end of exposure must be 21.2 sec. ± 0.1 sec. If different act on trimmer R40 (Speed 2) located on power board A1 (turning clockwise time becomes shorter) until the correct value is obtained.
12. Restore jumper X22 on the CPU in position pin 5-6 and make an exposure: exposure time read on the display of the hand control at the end of exposure must be 16.8 e 17.2 sec.
NOTE: Repeat the procedure until corrects readings are obtained. 13. If it's not possible to reach the correct times or it's necessary to
replace the Power board for different reasons, following the
adjustment procedure above described (steps 8 ÷ 12).
14. Turn OFF the unit and insert on the Power board the connector X9.
15. Restore the cover of the electronics cabinet and the covers of the rotating group.
16. Check correct operation making a panoramic exposure.
17. In case replacing the Power board and the motor the problem is not solved, it’s necessary to verify that the equipment is not making exposures in PAN Adult considering the PAN child and vice versa. In this case it’s necessary to verify the rotation angles and the start-stop microswitches following instruction in paragraph 7.9.1
(steps 8 ÷ 23) and 7.7. NOTE: In case replacing the Power board, check the output current (mA) following instruction in paragraph 7.4.
