I have a HP Color LaserJet 2840. If I am ... My Color LaserJet 2840 will only print on the right side of the page, how can I fix this? ... If I am copying or printing from the computer, the printer will only print the right side of the page. ... something obstructing the laser scanner blocking that side of the media path.
RE[place the transfer belt, open the right door, that shiney belt is the image trans fer belt that has the image on it to be placed on the media (paper) right above it is there a small plastic device in the middle that looks like it could cause your dots it was bad design that little thing prevents paper from riding on the belt
Your dlp chip is going bad and cannot be fixed economically. Several of the mirrors on the chip are hanging up and they won't come back. It will just get worse. My Sharp XR32X is doing the same thing. New projector time.
dots printed are from the cartridge, you proved that with the change to the old one. If the fuser was faulty, it would repeat the dot 2.5 times down an 8.5 x 11 page
Replace the cartridge and please use HP , remanufactured cartridges fail prematurley and usually wind up costnig more in service and repair/exchanges.
dots are usually always caused by the drum..drums are very easy to replace..(you don't even need a screwdriver)
remove the unit that the toner sits into..it's called a process unit..comes out as a whole with the toners...
next open left cover..
remove waste toner bottle. (drum sits right above it!!!
next remove drum by pushing on grey button and pulling drum
out the left side of the printer.
as far as the jam message you might need to replace tray feed tires located up under the machine
These dots may be called as "Garbage Valley" This means ur printer has got lots to print but it was stopped due to certain reason. I'll ask u to go through ur printer manual & print atleast 5 pages of garbage valley & while u do this, i'll ask u to reinstall ur printer driver. Hope it works out. Thanks
Hi Jay, do you have any idea how many discs have been printed with this Everest Printer?
Your issue sounds like a hardware error, not an issue with the software you are printing from. Most likely the printhead needs to be replaced, or the control board. Printhead replacement costs approx $1200.
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.
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.
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.
