Question about Xerox Phaser 1235N Laser Printer

Grey haze on all the printouts

Hello there, I would be really grateful if someone could suggest what might be wrong. We have changed the image drums and I have just purchased a new black toner and managed to buy a fuser since a friend suggested on his printer (different make) that was the solution. What do you think? A big thanks!

You should always use Original Equipment replacement drums, fusers and other devices made to the specification of the manufactures product. This will eliminated problems such as lines, blurring, hazes, and modeling. I some cases using other than OEM products can void a MFG Warranty.
I would suggest doing a very thorough cleaning of the interior of the printer. Remove and replace the hardware (Drum/rollers) and start fresh. Once that has been done, the printer will do a reset and start up like new. If it was cleaned properly, all current prints should be perfect. Other than that, any haze or poor reproductions thereafter would be related to a malfunction of the printer itself.

How Brave is Jan?

Doubt it be the fuser(100 000life), "just magenta dots".... fuser would be "all smudged" or "black marks" , "the print rubs off" , "paper is creasing or jamming"

Can prove it by stopping a print (open door) when paper is1/2 way threw machine, you need to stop it before it goes threw the hot bit, so you can tell if the hot bit (fuser) puts the marks on the paper.

Transfer roller one would expect to effect whole print Smudged/Faint,uneven density

It will be the imaging unit ( 30 000 pagelife Ouch$ ) or possible leaking toner (if aftermarket)

Remove imaging unit and inspect film you should find image of lines, dots are usually chips or sticky stuff on drum surface, carefull no oily human fingers on surface please.

When stopping machine mid print and perfecting your timing, pull out the imaging unit and look at replica of your print notice if marked and where.

Hope this helps

I had this problem when I used a generic toner. I installed a xerox cyan toner, then printed many sheets of a large blue rectangle. After about 15 pages the blue started to spread into the shape, after 30 pages the blue was back. Printing a lot of blue was necessary to get the new toner thru the system.

SOURCE: Xerox Phaser 6360 Black Toner prints Light Grey

I have had to repair a few of these. Take off the sides and back of the 6360. You'll see the hoses that feed into the laser. The black one becomes unplugged from the laser. All you have to do is plug it back in. The next step can be kinda messy. Take out the black toner cartridge, and spin the motor backwards. You'll know you're going the right way because it won't turn the other way. Cycle the gear where the toner sits for about 2 revolutions. Reassemble and you should be good to go!

This thing took me 6 days to figure out the first time. Haha!

Please vote on my solution! Thanks!

After changing the ink catridges and resetting the drum fuse lately (note: it is known that the fuse will be blown off after certain number of prints but otherwise is in good condition), my Epson Acculaser...

The repeating image is a ghost image, and here is described what it can be. Probably if you solve this, you also solve the red-dot problem. If possible, I would suggest to replace the wiper blade.
Repeating images on laser printerThis likely means a faint ghost of the main printout at a distance equal to the circumference of one of the rollers or photosensitive drum.

Depending on where the problem originates, this could be a bad wiper (cleaning) blade, faulty corona, or incomplete fusing.

  • If the distance between successive images is equal to the circumference of the photosensitive drum, it is a wiper blade, erase lamp, or corona problem.A residual latent image or residual toner is sticking to the drum and not being properly cleared.

  • If the distance between successive images is equal to the circumference of one of the fuser rollers, then the fusing may not be complete due to damaged rollers or an incorrect temperature setting.

It is easy to determine where the problem is located: Interrupt a printout in mid-stride (where part of the paper is between the toner/developer and fuser. If the un-fused image has ghosting, it is a fault in the area of the drum

Poor fax printout quality

I would say you have a bad drum / toner cartridge.

Stuff you receive with vertical lines is probably the sender's dirty scanner.

Problem with phaser

Phaser 2135 Printer: Resolving dirty looking background or gray haze

Description: Tiny speckles of toner scattered all over the page, even in areas of the page that should be blank.
  1. Make sure the media being used is supported by the Phaser 2135 printer.
  2. Inspect imaging drums for any signs of leakage or excess toner that could be falling onto the print as it travels though the printer. Any leaking imaging drums should be replaced.
  3. Verify environmental conditions. See article Dealing with humidity, humidifiers. If the environmental conditions are not within the specified range, the printer should be moved before trying to troubleshoot the cause to the background toner.
  4. Determine if any of the imaging drums were exposed to light for an extended period of time (more than 10 minutes). If so, then Replace the imaging drum. (Xerox is not responsible for any imaging drums that have been damaged by over exposure to light.)
Additional Recommendations:
Background toner may increase, if printing occurs at temperatures towards the higher end of the specified operating temperature range. For this reason, it is recommended that the printer be moved to another area if at all possible.
In addition, very smooth media types such as glossy; allow toner to more easily scatter about the page prior to becoming fused. Try using a less smooth media if at all possible.
