PARTS REPLACEMENT
This section describes the procedure for replacing the parts, assemblies and units in the field.The replacing procedure is given for detachment. To attach, use the reverse procedure.
2.1
Precautions in Replacing Parts
(1) Before replacing the parts, be sure to remove the CA cable and the interface cable. (a) To remove the AC cable, always use the following procedure. 1 Flip the power switch of the printer off (to "O"). 2 Pull the AC inlet plug of the AC cable out of the AC receptable. 3 Remove the AC cable and the interface cable from the printer. (b) To connect the printer again, always use the following procedure. 1 Connect the AC cable and the interface cable to the printer. 2 Insert the AC inlet plug into the AC receptacle. 3 Flip the power switch of the printer on (to "I").
Disconnect
Connect
(2) Do not disassemble the printer so long as it operates properly. (3) Minimize the disassembly. Do not detach parts other than those shown in the replacing procedure. (4) For maintenance applications, use designated tools. (5) Follow the order instructed to disassemble the printer. Incorrect order may damage the parts. (6) Small parts such as screws and collars tend to get lost, so temporarily place and fix them in their original positions. (7) When handling ICs and circuit boards such as microprocessors, ROMs and RAMs, do not use gloves that likely to have static. (8) Do not place the printed circuit boards directly on the printer or the floor.

Change the default PDL for each brand. PDLs that are disabled in this Menu will not be displayed on User Menu or Adomin Menu's PERSONALITY. When print data in the PDL language set to DISABLE is received, the printer will display INVALID DATA and discard received data. (HPGL/2 is under development, and there is no plan to implement as yet in the product. ) The PDF function requires Adobe Postscript; thus, switching ON/OFF of PDF alone is disabled. (Setting Adobe Postscript on DISABLE will set the PDF function to DISABLE as well. ) On the PX711/713, neither Adobe Postscript nor PDF can be set to DISABLE. (They are to be always set to ENABLE for use. Even if they are set to DISABLE, the printer processes the data it receives. This item is incorporated only in the menu ahead of time for future extension. )

DIAGNOSTIC MODE XX.XX.XX
Switch operations and LCD displays in Engine Self-diagnostic Mode depend on the instructions from the Engine F/W; hence, they are different from the operation spec in the Controller F/W. Engine Self-diagnostic Mode is excutable even if the Controller board is removed. For details, see the Engine Unit spec as needed.

ID Check Pattern Printing ( " TEST PRINT MENU " item ) This pattern can be used for the cause investigation (specifying of color(C,M,Y,K) of the problem item, the confirmation of the periodicity) of the following problem that it originated in ID, the LED head. It is composed of CMYK color 20% duty each of the patterns (print 2 pages).

Engine maintenance mode Three modes from Level 1 to Level 3 are in the engine maintenance mode. Level 1 is a mode that checks the media transport and basic movement of the print system. Level 2 checks the counter for consumables and tests the correcting function of color displacement, and is a mode that does not require special knowledge. Level 3, on the other hand, requires special knowledge for handling the process parameter setting and is contained in the independent experimental element of PU. Basically, levels other than Level 1 should not be used.

The status returns to that described in 2 after driving 10 seconds, and the unit will start driving again be pressing the corresponding switch.
· The drive control conditions listed in Table 3-2 must be fulfilled in order to drive the corresponding unit. A unit cannot be driven without fulfilling the conditions, and if attempted, instructions will appear in the bottom display line. · For clutch solenoid, ON and OFF is repeated for normal print drive. (For those that cannot be driven independently due to their mechanism, drive with the motor.) 4. A driving unit is stopped by pressing the 7 key. (The display of the corresponding unit is maintained.) 5. Repeat Steps 2 to 4 as required. 6. Press the 4 key to end the test. (Status returns to that described in 1.)
