I Have konica 7130 i can t Made L detection The

The L detect adjustment is done only after you have replaced the developer. On that older Konica copier the service modes are much different than on newer models. You need to enter something called 36 mode by holding the 3 and 6 keys while turning on the power switch. Under process adjustment you will find L detect. Again.....this is only done after changing the developer. The adjustment must be done prior to making any copies after the developer has been installed. If you are not a tech , I would call one for this level of service.

Go to Touch Panel adjustment you will see "+" to the 4 corner of the touch panel use pointed object point it MILD on the center of the 4 "+" . Off / On

Remove the drum cartridge, then remove developer unit, then the charge housing above the drum the remove the drum do not touch it has to be done from the side of drum. once removed then is sensor that has a white cover on it, there is also a clear one white one is in the rear on the left side clean DO NOT USE A VACUUM Cleaner the static electricity will destroy the sensor. Then re install. run all required check . Unless you know what you are doing get a qualified Konica Minolta Technician Has to have Konica Experience You have a legacy Konica machine

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

F 28-01 High voltage power supply abnormality.
Ihe charging ON/OFF operation has been performed five consecutive times since the charging trouble detection signal was detected at start of charging.If there is a paper in copying process when this jam occurs,the machine stops after completion of copied paper ejection.Verify the charge wire,change and the holders.Check the high voltage unit.
F - 28 -02 Toner transfer wire malfunction
F - 28 -03 Toner separation wire.malfunction

off the machine ,hold 2and 5 simultenously then on the copier press software switch then go the # 16-0-0

You must perform ATDC sensor gain procedureF8 and AIDC sensor F5 perform.

How to reset an F34, F35, or F36 code.
Solution:
To clear the code, perform the following:
1. Turn the machine OFF.
2. Enter the 25 mode, (turn the machine ON, while pressing the 2 and 5 keys).
3. Select 1: Software Switch Setting.
4. Use the arrows on the LCD to select dipswitch 3-1.
5. Touch the OFF key on the LCD to change the data to 0.
6. Press RETURN.
7. Power the machine OFF/ON to exit the 25 mode. PLEASE. NOTE;
THIS IS ONLY TO RESET THIS CODE ,IF IT CAN;T BE CLEARED THAN YOU NEED TO Replace the temperature sensor assembly

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.

Attachments:this is additional information on f-26-2
and i have given you info on f-26-3
you should revue all the information
hope that helps

what happens when u run L-detect. Make sure the sensor near the drum sep claws in the drum unit is clean. Any toner or setting powder on this semsor will give u errors while running L-detect.
