  Preparation Prior to proceeding with the disassembly procedure, (1) Be sure to back up the machine information and user data into an external memory. memory. If the main PCB is replaced, restore the backup data to the new main PCB after completion of  reassembling. Failure to back up the machine information requires the ink absorber box and flushing box to be replaced after replacement of the main PCB. For detailed backup and restoration procedures, refer to Chapter 9, Section 9.4.10 "Backup of Machine Information (Function code 46) (User-accessible)."

replacing the main PCB, make sure that the machine information has been  backed up in an external memory. memory. Failure to back up the machine information i nformation requires the ink  absorber box and flushing box to be replaced after replacement of the main PCB. For detailed backup and restoration procedures, refer to Chapter 9, Section 9.4.10 "Backup of  Machine Information (Function code 46) (User-accessible)." Caution: Before accessing the main PCB, make sure that the power cord is unplugged from the electrical outlet and the telephone line *1  is disconnected; otherwise, an electric shock could occur. Vorsicht: Bevor

Sie auf das Mainboard zugreifen, stellen Sie sicher, dass der Netzstecker aus der Netzsteckdose gezogen und das Telefonkabel (nur für MFC) entfernt ist. Andernfalls kann es zu einem Stromschlag kommen. At the time of removal of the main PCB, untightening screws should be preceded by disconnection of the harnesses and flat cables, and at the time of installation, connection of the harnesses and flat cables, by tightening of screws. Observing this sequence prevents harnesses and flat cables from getting crushed or damaged by screws or screwdrivers.

Caution:

(1) Disconnect Disconnect the followi following ng harnesses harnesses and flat flat cables from from the main PCB. PCB. Do not remove the screws from the main PCB before disconnecting harnesses and flat cables. Caution:

After disconnecting the flat cables, check that each cable is not damaged at its end or  short-circuited. When connecting the flat cables, do not insert them at an angle. After  insertion, check again that they are not at an angle. Note:

Assembling Notes When mounting the duplex unit on the lower cover, follow the steps below. 1) Bring the duplex unit inside the lower cover, with the left end first. Fit the left and right supports over the paper ejection roller shaft and fit the metal hooks into the openings  provided in the lower cover. cover. 2) At the right end of the duplex unit, snap the DX spring lock into place to secure the duplex unit. Then, route the DX cover sensor harness through the opening provided in the lower  cover. For the routing of the harness on the top of the lower cover, see the illustration given on the next page. 3) At the left end of the duplex unit, set the DX spring lock on the two harnesses (switchback   paper detection sensor sensor harness and DX cam switch harness) and snap it into place to secure the duplex unit. Then, route those harnesses through the cable guide (shown on the  previous page) and the opening provided in the lower cover cover.. For the routing of those harnesses on the top of the lower cover, see the illustration given on on page 6-57.  page 6-57. 4) Set the DX inner covers R and L back into place.

CHAPTER 9 MAINTENANCE MODE This chapter describes the maintenance mode which is exclusively designed for the purpose of checks, settings and adjustments of the machine using the keys on the control panel*. * In operations for the maintena maintenance nce mode in models with touch panel, ke keys ys of the software keypad displayed on the touch panel are also used. Only when a key needs to be limited to the one on the control  panel or on the touch panel, this chapter describes a key, for example, as "the Copy key on the control  panel" or "the Scan key on the touch panel." If a description says just "the 5 key," you can use either the 5 key of the numerical keypad on the control panel or the 5 key of the software keypad on the touch panel.

In the maintenance mode, you can update memory (EEPROM: electrically erasable programmable read-only memory) contents for optimizing the drive conditions of the head/carriage unit or the paper  feed roller and paper ejection roller in the engine unit, if those units have been replaced, or for setting the CIS scanner area, for example. You can also customize the EEPROM according to the shipment destination of the machine concerned. In addition, you can perform operational checks of the LCD, control panel PCB or sensors, perform a print test, display the log information or error codes, and modify firmware switches (WSW). NOTE: This chapter includes descriptions of facsimile functions which a DCP does not support.

Basically, the maintenance-mode functions listed on the previous page should be accessed by service personnel only. However, you can allow end users to access some of these under the guidance of service personnel (e.g., by telephone). tele phone). The user-accessible functions (codes 10 to 12, 46, 52, 53, 66, 75, 76, 80, 82, 87, 88, and 91) are  shaded   in the table given on the previous page. Function code 10 accesses the firmware switches, each of which has eight selectors. You should not allow end users to access all of  those selectors, but you can allow them to access user-accessible selectors which are  shaded  in  in 4.. the firmware switch tables in Appendix 4 The service personnel should instruct end users to follow the procedure given below. (1) Models without touch panel  Press the Menu, Black Start (Mono Start), and Menu keys in this order. The "

Function To keep the paper feeding performance in the best condition for quality print, the controller  optimizes the rotation of the paper feed roller, using the correction value stored in the EEPROM on the main PCB. If you replace the engine unit or head/carriage unit, you need to update the paper feeding correction value according to the procedure given here.

(8) Out of the the three three rows of of the "PF adjust adjust check" check" pattern pattern (on (on the page the page 9-32), 9-32), check the middle row and select the block that is the least uneven print. Make a note of that block number. If the least unevenness seems to be far to the left of -8, regard it as -8; if it seems to be far tto o the right of +8, regard it as +8. In this case, you need to check whether the paper feed roller  and head/carriage unit are set into place. (9) Enter the number number of the the least uneven uneven block block found found in step (8). For example, if the number of the least uneven block is +4, press the 4 key while the "PF ADJ NO. +0" is displayed on the LCD. If the number is -4, press the

key to display the "PF ADJ NO. -0" and press press the 4 key.

(Note) If the head/carriage unit is replaced with a spare part having a round, blue seal on its left side (shown in Appendix 1, "(2) Head property labels") labels"), perform the head replacement purge. If it is replaced with the one having no seal, perform the initial purge.

This machine counts all purge operations and flushing operations performed since produced in order to prevent the ink absorber box and flushing box from overflowing with drained and flushed ink, respectively. An initial purge, for example, advances the counter by 155+ 331 = 486. When the purge or flushing counter approaches 12480 or 619318182, respectively, the "MACHINE ERROR 46" appears, and further purge or flushing operations are prohibited. Replace the ink absorber box and flushing box, and then reset their counters. (Refer to the next  page for the reset procedure.) 9-50
