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).

I may be able to get the manuals for a nominal charge. bkbell@brianbell.net

SOURCE: Konica Minolta 7022- How to clean- Getting Dark Lines on Copies

Beings as it is close to 100k, it is due for a PM (preventative maintenance) kit to be installed (this model has a 100k PM cycle), and also a web, corona wires, charge grid, and feed rollers (if worn) should be replaced at this point, and of course cleaned.

The drum and developer "should" last 200k (this can vary greatly).

$200 for a general cleaning on that series machine... that's entirely too much, and he will most likely tell you it's due for a PM. A competent technician would be able to install the kit, replace the above parts in under 2 hours easily.

I wish I could be of more help, but given that is almost at the end of its PM cycle, it could be anything.

Open the top cover. Remove the drum (part with long green handle). Below the drum you will see a strip of glass about 4-5 inches long. Take a cloth and wipe across the glass.

This will normally clear up any white lines in your print.

My copies are coming out with a horizontal black line through the middle of the page. I have a cannon C330D copy machine. And would like to fix this myself if possible. Any suggestions?


If you can wipe off the line with your hand its probably your fuser roller or pressure roller thats need to be changed. IF the line is fused properly and cannot be wiped away you might have a damage drum unit.

KONICA 7020 - Blank copy


I have never heard of a developer moving backwards!!!!!!!!!!!!!!!!???
the motor that runs it, the .... there is too much involved to mention. A developper moving backwards will spill so much toner in the machine anyway.
If you get a copy and then it goes blank, that tells me you have a problem with the SEPERATION UNIT, it may be shorting out causing the paper to rise against the drum giving you blank copies.
A blurr copy tells me there is a problem with the Scanner/Optics area. maybe the rails that the scanner run on are too dry or has a problem, the optics(mirrors) may be misaligned.
Not sure what you mean by (hanging) ??

Horizontal black and white lines are coming on copy


you don't mention whether the document you are copying also appears on the paper.If it does you could have 1 of 2 problems-
The drum cleaning system could be at fault or-
the fuser roller has picked up some **** easy test...... run copies and when the 1st copy edge appears switch OFF. This is a crash stop.Now examine the sheets in there.Is the stripe on the copy before the fuser (Heat) roller? If yes you could have a drum cleaning problem, usually fixed by changing the drum module.If no and the stripe appears after the heat roll, the problem is with the fuser system,dirty rolls etc. There are a number of other problems with stripes, but you have to start somewhere! If the document does NOT appear on the copy, forget all above, could be scan or ROS problem
