F26-1 at power up. [Description] F26-1 at power up.
[Solution]
PROBABLE CAUSES:
1. The TDS (Toner Density Sensor), in the developing unit, has detected a depletion of toner.
Note: This may have been caused by the customer making an excessive amount of copies while the machine was out of toner. It may also be caused by a bound toner addition system.
Clean all toner from the toner recycle and toner supply assemblies. Confirm that the gear mesh between the toner supply auger drive gear and toner supply motor (M4) is flush. If toner supply conveyance is normal and the toner cavity is empty, install a new toner cartridge (Item #950236) and then perform the following diagnostic mode to replenish the developing unit with toner:
a. Access the 47 mode (power the copier ON while pressing the 4 and 7 keys).
b. Enter output code 54.
c. Press the START button.
Note: Toner will now be added to the developing unit and stop automatically when target level is reached, although it will not run any longer than 3 minutes.
d. Power copier OFF/ON to return to normal copy mode.
Note: Perform the following 25 mode software switch settings to minimize the amount of copies that can be made, prior to copy inhibit, when the ADD TONER message is displayed:
- Access the 25 mode (hold down the 2 and 5 keys at power ON).
- Select [1] (SOFTWARE SW).
- Using the up and down arrows, scroll to the following software switches and set them as follows:
a. 4-0 set to 0
b. 4-1 set to 0
c. 4-2 set to 0
d. 4-3 set to 0
- Power OFF/ON to return to normal copy mode.
Notes:
A. These setting will allow the ADD TONER message to be displayed immediately and only allow 100 copies to be thereafter.
B. Copier inhibit will automatically be released when a new toner cartridge is installed.

2. The toner conveyance gear is worn. The toner conveyance gear is driven by the toner supply motor located on the toner supply unit.
Replace the toner conveyance gear (p/n 26NA32680).

SOURCE: Konica 7020 copier

replacing the drum will not fix the F-26-2 code

the L detect will need to be done on the copier to clear this code. it will require developer. never run this adjustment without replacing developer. the 7020 and 7030 series will error out if the developer is replaced and L detect is not done or vice-versa

to fix this replace developer then cut the machine off. hold down the 3 and the 6 button while cutting the machine on, go to (1)voltage adjustment then scroll down through approx 6 or seven adjustments to L detect. make sure all the doors are closed and the copier is ready. hit start, the machine will take about 5 minutes to complete this adjustment, it will display "ok" in the screen when it has successfully completed the adjustment. if it displays 006 pull the developing unit out, and clean the contacts towards the backof the developing unit. sometimes developer droppings can cause this code.

after it has completed L detect now cut the machine off, hold down 2 and the 5 button while cutting it on. go to counter and reset the pm counter.

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 minolta EP2010 error code c05

I have a Konica Minolta CSPRO EP1054 (in the Middle East)

I accidentally plugged the EP1054 copier into a 110V outlet instead of the 220V. Immediately the malfunction code (error code) of "C05" appeared along with the "Call Tec Rep" indicator light (wrench).

I followed the instructions posted by "Soul Visitor" ... i.e., I found the "Trouble Reset Switch" (not shown in the user manual) by opening the upper back panel and pressing the small black button in the lower right hand corner of the middle circuit board (green).

It worked perfectly!
