Copy quality Black & White copier. Copies come out lighter than the original, and adjusting the "image density" does not solve the problem.

Getting light print on b&w, changing density makes zero change. Toner changed, no effect.


Check whether you are running as Black and White or Gray Scale. Many printers only print straight black by using all four toner cartridges- Cyan, Magenta, Yellow, black. If are running colored print in black and white and u choose grey scale it will automatically give you a screened image as a light print.

Problem Cause Solution Colored lines appear. The exposure glass or scanning glass is dirty. Clean them. See "Maintaining Your Machine", About this Machine . Copies appear dirty.

On the control panel, select [Auto Density]. The reverse side of an original image is copied. Image density is too high. Adjust the image density settings. See "Adjusting Copy Image Density", Copy and Document Server Reference . The reverse side of an original image is copied. Auto Image Density is not selected. On the control panel, select [Auto Density]. A shadow appears on copies if you use pasted originals. Image density is too high.
  • Adjust the image density settings. See "Adjusting Copy Image Density", Copy and Document Server Reference .
  • Change the orientation of the original.
  • Put mending tape on the pasted part.
The same copy area is dirty whenever making copies. The exposure glass, scanning glass, or ADF is dirty. Clean them. See "Maintaining Your Machine", About This Machine . The same copy area is dirty whenever making copies.
  • The original that has already been printed is scanned.
  • Original Type is set to [Text / Photo], and an original with text and photographs that can hardly be distinguished from each other is loaded.
On the control panel, press [Generation Copy], and then begin copying. Copies are too light. Image density is too light. Adjust the image density settings. See "Adjusting Copy Image Density", Copy and Document Server Reference . Copies are too light. A light copy may result when you use damp or rough grain paper. Use recommended paper only and be sure its storage environment meets the recommended temperature and humidity conditions. For details about recommended paper and the proper way to store it, see "Recommended Paper Sizes and Types" and "Paper Storage", About This Machine . Parts of images are not copied. The original is not set correctly. Set originals correctly. See "Placing Originals", Copy and Document Server Reference . Parts of images are not copied. The correct paper size is not selected. Select the proper paper size. Parts of images are not copied. Even if you place originals in the ADF correctly, margin of a few millimeters on all four sides of the original might not be copied. Use "Create Margin" function to reduce the image of its original size.
For details about missing image area, see "Missing Image Area", Copy and Document Server Reference . images appear only partially. The paper is damp.

Copies are blank. The original is not set correctly. When using the exposure glass, face the originals down. When using the ADF, face them up. A moir? pattern is produced on copies. Your original has a dot pattern image or many lines. Place the original on the exposure glass at a slight angle. Black spots appear on the copy of a photographic print. Because of high humidity, the photographic print has stuck to the exposure glass. Place the print on the exposure glass in either of the following ways:
  • Place an OHP transparency on the exposure glass, and then place the print on the OHP transparency.
  • Place the print on the exposure glass, and then place two or three sheets of white paper on it. Leave the ADF open when copying.
White stripes appear on the OHP. Fragments of paper are stuck to the OHP. Use a dry cloth to wipe any paper fragments off the back of the OHP. The image on the back side of duplex copies has mottled blank patches or is smudged. Missing patches and smudges are caused by moisture leaking from the paper.
  • Do not install the machine in areas that are susceptible to low temperatures.
  • Use paper that has been stored where temperature and humidity conditions meet the limitations we recommend. For details about the paper storage conditions we recommend, see "Paper Storage", About This Machine .
  • Install the Optional anti-humidity heater. For details about the anti-humidity heater, contact your service representative.

There is an error code c-2558 showing on my machine konica minolta bizhub c452 please do let me know the proper remedy for it ASAP


Abnormally high toner density detected Black TRC sensor-

1. Correct the TRC Connection on the underside of the imaging unit if faulty
2. Reinstall black image unit
3. Change image unit
4. Change PWB-M
5. Change PWB-MFP

you can try # 2 then run 20-30 sky shops (copies with lid up to make black copies) put a white piece of paper over lead edge section of copy glass so you are only making 1/2 black copies if you don't the copy may jam in the fuser due to excess toner. after running copies turn machine off for 10 secs to reset and power backon. if problem continues I would change the image unit.

Gestetner 3245 dev.bias setting....


Hi how you doing the main problem with changing the dev bias is that the gap between the drum charge and dev bias has been brought closer and so more toner is being put onto the drum for image density.. I take it you have cleaned the optics on the scanner mirrrors and that the laser **** glass has been cleaned as these effect the copy quality too.. if the dev hasnt been changed at the pm intervals it slowly looses its charge holding capabilities.. you should change at least at the 160k marks to keep quality good.. you could also adjust the laser power up so you have a stronger image formation..hope this helps..if you know the machine I would take the laser unit out too and take the cover off to see if there a dust coating in the image mirrors as this can cause faint copies over a long period.. Good Luck A

2. Press Copy repeatedly until Set New Defaults appears.
3. Press until Yes appears and then press OK.

This should help you.

IMAGE TOO DARK ON GEI GRAPHIC ZOOMER POSTER BANNER SYSTEM


First I would give the optical area a good cleaning --- mirrors, lens, etc.. If this device has the 'slide' adjust for the image quality, the slide may have come out of the holder. Try seeming if the slide is seated properly. If this is the 'thumb / circle ' adjust, the POT ( value adjust on the board) may need to be reset. There is always the chance the the board is cracked or has a cold solider joint (pins) for the adjuster. IF you are inclined, that the cover off and check for crack, if no crack heat and re-solider the pins for the adjust switch.

White line and very, very dirty copies


the nealy black copies sounds like the drum is going, try adjusting the exposure to light, if it comes out with the whole page the same way but just lighter than change drum. White line sounds like there is something on the coronas.
