1154D215AA 1154D212AA 1154D213AA
Retarded Correct Advanced
The loop length is too long causing the paper to have too much slack.
A good length of loop is formed as the paper moves into the Fusing Rollers.
No loop is formed causing the paper to be taut.
7. If the timing is advanced or retarded, change the setting of Fuser Speed.
Adjustments
Retarded: Increase the setting. Advanced: Decrease the setting.
8. Check the length of the loop again and repeat the

Step before Replacement
Select List Output from the Service Mode Menu and produce the following lists: Image Processing and Counter.
NOTE
Check the settings of the following functions and make a note of them before replacement, as no lists will be produced for them. Setting 1: CH Cleaning, A6 Card Margin (4 × 6 Paper Margin) Setting 2: Paper Kind, Admin. Mode, RD Mode, Orig. Detect Sensor Machine Adjust 1: Fuser Temp. In addition, the settings in the User’s Choice of Utility are not printed. Check and make a note of these settings, too, as may be necessary.
Steps after Replacement
1. Clean the optical parts (PH Assy, Original Glass, lens, mirrors, Lamp).
2. Add fuser oil up to the required level.
3. Replace the Toner Collecting Box with an empty one, or dump toner from the Toner Col­lecting Box.
4. Remove the Rear Cover to prevent predrive from being initiated.
NOTE
Since the new Backup Memory RAM has no old developer data, the copier may detect a malfunction as it relates to the Developing Unit if predrive is initiated.
5. Using Touch Panel Correct, correct the position of the keys on the Touch Panel.
6. On the list of Life 3 (Others) available from Counter of the Service Mode Menu, select Toner Collect and press the Clear key.
7. Since the Touch Panel language is English, select “Language” of “User’s Choice avail­able from Utility and change the setting as necessary.

4-4. FLASH MEMORY
Software has conventionally been upgraded by replacing ROM on each board. This copier employs flash memory for the system control IC mounted on the IR Control Board (on the IR side) and Master Board (on the engine side). Its contents are reprogrammed easily by performing the following steps using the IC card (memory card), in which data has been previously downloaded.
NOTE
NEVER remove or insert the memory card with the copier power turned ON.
(1) Using a Single Memory Card
Memory Card Cover
IR Control Board
Master Board
Hopper Unit
1154D274AB
1179D069AA
1. With the Power Switch in the OFF position, unplug the power cord from the power outlet.
2. Remove the Hopper Unit.
3. Remove two screws and the memory card cover.
4. Mount the memory card in the IR Control Board (upper one) or Master Board (lower one).
5. Plug the power cord into the power outlet.
6. Turn ON the Power Switch.
This lets the copier start rewriting the data.
The Touch Panel shows “Downloading.”
7. On the Touch Panel, check that the data has been properly rewritten (in which case the message Downloading Completed appears) and check the checksum (Check Sum: OOOO on the panel).
The illustration represents the Touch Panel display when the Master Board has been rewritten.
1179D532AA
D-150
Page 58
8. Unplug the power cord from the power outlet.
NOTE
Do not turn OFF the Power Switch at this time.
9. Remove the memory card and turn OFF the Power Switch.
10. Using the same procedure, rewrite the data on the other board.
11. Check that ROM Version of State Confirm available from the Service Mode Menu shows the version indicated on the memory card.
(2) Using Two Memory Cards
Memory Card Cover
IR Control Board
Master Board
Hopper Unit
1154D274AB
1179D039AA
1. With the Power Switch in the OFF position, unplug the power cord from the power outlet.
2. Remove the Hopper Unit.
3. Remove two screws and the memory card cover.
4. Mount the memory cards in the IR Control Board (upper one) and the Master Board (lower one).
5. Plug the power cord into the power outlet.
6. Turn ON the Power Switch.
This lets the copier start rewriting the data.
The Touch Panel shows “Downloading.”
7. On the Touch Panel, check that the data has been
properly rewritten (in which case the message Downloading Completed appears) and check the checksum (Check Sum: OOOO on the panel).
1179D522AA
D-151
Page 59
8. Unplug the power cord from the power outlet.
NOTE
Do not turn OFF the Power Switch at this time.
9. Remove the memory cards and turn OFF the Power Switch.
10. Check that ROM Version of State Confirm available from the Service Mode Menu shows the version indicated on the memory card.
(3) Writing upon Replacement of IR Control Board/Master Board
If the IR Control Board or the Master Board is replaced individually, load the memory
card in the board that has been replaced for data writing.
If both the IR Control Board and the Master Board are replaced at the same time and if a
single memory card is to be used, start writing the data with the Master Board side. The copier does not rewrite data if an attempt is made to write data first for the IR Control Board.
(4) Action to be Taken When Data Transfer Fails
When the message Engine: N.G or IR: N.G appears on the Touch Panel, it indicates that data has not been properly rewritten. In this case, perform the following steps. If two memory cards have been used, only the specific board with which data transfer failed is displayed.
1. Perform the data rewriting procedures again according to the above steps.
2. If the sequence is not normally terminated, change the memory card for a new one and try another rewriting sequence.
3. If the sequence still fails, replace the Master Board or IR Control Board and then try another rewriting sequence. If the message Engine: N.G appears, replace the Master Board. If the message “IR: N.G” appears, replace the IR Control Board.
