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.

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

Darkening the copies


Here's information from the HP manual:
Use the copy features
The HP All-in-One enables you to produce high-quality color and black-and-white copies on a variety of paper types, including transparencies. You can enlarge or reduce the size of an original to fit a specific paper size, adjust the darkness of the copy, and use special features to make high-quality copies of photos, including
borderless copies.

Press Copy repeatedly to display the appropriate menu. The following menus are available:
– Number of copies
– Reduce/Enlarge
– Copy Quality
– Copy Paper Size
– Paper Type
– Lighter/Darker
– Enhancements
– Set New Defaults
2. Press the until the appropriate setting appears.
3. Do one of the following:
– To change more settings, press Copy.
This selects the current setting and displays the next menu.
– To start the copy job, press Start Color or Start Black.

To save the current settings as defaults for future jobs
1. Make any needed changes to the settings in the Copy Menu.
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.
