Details Subject:
Background, overtoning, and/or F26-x codes.
Description:
Background, overtoning, and/or F26-x codes.
Solution:
PROBABLE CAUSES:
1. Overtoned developer.
Install fresh developer (PCUA 950237) and run the L-detect adjustment. To run the L-detect adjustment, perform the following:
a. Enter the 36 mode (power the copier ON while pressing the 3 and 6 keys).
b. Press [1. HV adjustment].
c. Press [Next] several times until the display reads [HV adj (L detection adj)].
d. Press [Start].
e. When the adjustment is complete, the machine will stop and a value is displayed in [RESULT].
f. If the developer was sampled properly during the L-detect adjustment, the value displayed in [RESULT] will be in the 60-75 range.
g. If the L-detect adjustment [RESULT] value is outside of the 60-75 range, than the TDS (toner density sensor) should be checked.

2. Failed TDS (toner density sensor).
To check the TDS, perform the following:
a. Remove the IP unit (if an IP unit is installed).
b. Remove the rear and left rear side cover.
c. Remove the board cover/D (p/n 26NA73280) for access to the PRDB.
d. Enter the 36 mode (turn the machine ON, while pressing the 3 and 6 keys).
e. Select [1. HV adjustment].
f. Press [NEXT] several times until the display reads [HV adj. (Toner auto supply)].
g. Locate TP14 (TDS AN) in the middle of the PRDB above CN 25.
h. Using a voltmeter (20V DC range), place the red meter lead on TP14 and the black meter lead to frame ground.
i. Press the START button on the control panel.
j. The analog voltage reading on the volt meter during sampling should be (with properly toned developer) between 1.2 and 2.0VDC. If the voltage reaches 2.0VDC, M4 (toner addition motor) will turn on and add toner. When the toner auto supply adjustment is finished the voltage should read approximately 1.8VDC.
k. If the voltage reading is not within this range, replace the developer (PCUA 950237), TDS (p/n 26NA88040) and run the l-detect adjustment while monitoring TP14 on the PRDB.

3. Failed write unit (the TCSB monitors dot pattern patches created on the drum and adjusts the laser output for Maximum Power Control).
If developer has been replaced, L-detect run, the TDS voltage checks, and the developer is still overtoning (M4 continuously adds toner), replace the write unit (p/n 26NA-6503).

4. Clogged machine filters.
Check all machine filters to verify they are not clogged. Clogged cooling fan filters prevent proper ventilation which can cause the adhesive on the write unit glass cleaner to melt due to high internal temperature, causing smears on the glass.

SOURCE: Konica 7145 F-51-2 Error

Code F51-2 at start-up.
Description:
Code F51-2 at start-up.
Solution:
CAUSE: Code F51-2 may be caused by a failed M11 fixing motor. To determine whether or not the motor has failed, use this procedure:
1. Enter the 47 mode (I/O check mode).
2. Input "40".
3. Input multicode "0". If the M11 motor turns, it is good; if it does not turn, the motor has failed.

SOLUTION: Replace the M11 motor (p/n 56AA80072 for 7222/7228/7235 and p/n 56GA73430 for 7145) if it has failed.

hope that help!!!

Konica 7145 i have an error message 0006 I have replaced drum in drum assy. it gave me an f26-3 error message performed L detection now it gives 0006?


Check Toner control sensor board, on drum unit behind drum, is clean, try L-detect then, try it a couple of times. If that fails you will then have to change developer, and perform L-detect.

Hi Just bought a Konica 1212 and P.27 keeps flashing. Please can you help. I have no instructions.


Only developer should be added during a new machine set-up so that toner does not cover the TDS sensor.
To eliminate the code:
a. Access the 47 mode, output code 40, and allow the main motor to run for approximately one minute. Any excess toner surrounding the TDS should mix with the developer.
b. Perform the L-detect adjustment again (47 mode, output code 51).
c. If the problem remains, repeat steps a and b.
d. If this does not correct the problem, replace the developer and perform the L-detect adjustment.
