c. It may be necessary to readjust paper RESTART TIMING for both the main body and the

RADF to have the image properly aligned after changing the READ POINT ADJUSTMENT.

d. Information pertaining to RESTART TIMING PROCEDURES can be found in the

7020/7025/7030/7035 service manual (3/2001) starting on page 4-42.

CAUTION: Excessive adjustment to the READ POINT position will cause copy density to be lighter

when copying from the RADF.

Notes: Never use paint solvents, such as benzene or thinners, to clean any portion of the copier.

Auto layout application centers the image from front-to-rear, but not from lead-to-trail.DESCRIPTION: SOLUTION ID:

83603

SOLUTION:

CAUSE: Firmware bug.

SOLUTION: Flash the 7020 with the latest firmware. System control firmware level 25 and Image

processing firmware level 23 will resolve this problem.

Note: The 7020 firmware is currently available on the Konica [[FTP site| FILE V:\text\CBC009.txt

NEW NoWordWrap]]. Refer to the [[FTP_ user site.txt file| FILE V:\text\CBC010.txt NEW

NoWordWrap]] on the FTP site for detailed information concerning site contents. [[Internal Link for

USAGE:

Scratch lines around the circumference of the drum during setup.DESCRIPTION: SOLUTION ID:

91238

SOLUTION:

CAUSE: The transfer guide plate assembly (p/n 26NA-2610) is out of alignment and is contacting

the drum. The transfer guide plate assembly is attached to the transfer side of the T/S corona unit.

SOLUTION: Replace the T/S corona unit (p/n 26NA-2600) and drum (Item #950253).

Notes:

1. A procedure/specification is not available to properly adjust the transfer guide plate assembly.

2. Use the standard Konica parts warranty replacement procedure to receive full credit for failed

parts.

3. The occurrence of this problem is very low. Approximately 0.1% of machines may be affected,

beginning with serial number 26NE00001 through 26NE09434.

USAGE:

No power. Display is blank with only the green data light ON.DESCRIPTION: SOLUTION ID:

88532

SOLUTION:

PROBABLE CAUSES:

1. System firmware is corrupt; possibly due to a sudden loss or surge of AC power supplied to the

copier.

Flash both the system and image firmware. If the 7020 will not allow access to 25 mode, perform

the following:

a. Power the copier OFF (SW2 [operation panel] first, then SW1 [left rear]).

b. Prepare the laptop PC or the ICW TOOL for flashing and connect it normally to the 7020.

c. Power the copier ON (SW1 [left rear]) first, then SW2 [operation panel]).

d. Send the system firmware from the laptop PC or the ISW TOOL to the 7020. The green data

light will begin blinking.

e. The LCD display will reappear, in the normal ISW flash mode screen, when the system

firmware has completed its flash.

f. Flash the image firmware.

Notes:

I. For procedures on how to flash the firmware, refer to 7020 service manual (3/2000) pages

9-1 through 9-36. Currently system firmware is at level 24 and Image firmware is at level 22.

II. It is highly recommended that all 7020's be plugged into a power tamer device (p/n 11515C)

for added protection.

2. Failed overall CB. A sudden loss or surge of AC power supplied to the copier may have caused

the overall CB to fail.

Replace the overall CB (p/n 26NA-9300).

Notes:

a. It may be necessary to flash the copier firmware because of the possibility that the

replacement overall CB may not have the correct firmware level to match the level of the

peripherals firmware. It is also possible that the replacement overall CB may not have any

firmware loaded at all.

b. If the replacement overall CB does not have firmware loaded, the 7020 will power up with

only the green data light ON. In this case, flash machine in the same manner as described above.

USAGE:

FK101, TCR report shows the results, but faxed image is reduced or sometimes will be

blank.
