The guest it correct. The TDC sensor controls the developer. They do go bad and should be replace if you can't get it to calibrate.

You have a toner detect problem.You will probably need to replace the TDC sensor in the developer unit.If you want you might be able to check the data control,mode 47-01&02.or 47-57 for the toner level power signal.

Error code F 26-3 on Konica 7022


Sir/mam, you might have a bad drum density sensor or it was not cleaned or was destroyed by static electricity, if a vacuum cleaner was use to remove the old developer, NEVER use a vacuum cleaner for that procedure. Remove the drum and will see a small sensor near where the cleaning blade sits need to clean it replace it. Worse case the main control board is bad that what sensor talks to .Was the L Detect procedure run after the developer was replaced, and before you replaced the developer did you clear the developer counter, to let machine know it has new developer, because clearing the counter is the only way the copier has new developer, did you clear the counter for the new drum? The machine use the counters to determine voltages for certain assemblies. If L detect was not run and copies or prints where made get new developer and start over.

Konica 7022 F-26-3/2 L detect 0004 Konica 7022


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.
