Evenly spaced, repeated marks on the page.

Evenly spaced, repeated dots, or a fine line from the top of the page to the bottom means that your toner cartridge OPC drum has been damaged in some way. The only way to solve this problem is to replace the cartridge with another one.

Printing is too light or too dark.

The most common reason that your printing is too light or too dark on the left or the right side is that the doctor blade is set incorrectly. Another reason is that you need to set your print density setting on your laser printer. Check your printer manual for information on this procedure, or if you cannot find that manual email us at theveteran@proudvet.com . We are familiar with many types of laser printers.

Random black vertical lines.

A dirty cartridge corona wire mostly causes random black and vertical lines. To solve this problem you need to clean the wire with the brush provided with your laser printer. It would be good to look at your manual for specific instructions for your laser printer. Also, solid round dots or round circles on the left side of the page. If the vertical lines do not go away an electrical charge is jumping across the corona wires. The cartridge needs to be replaced.

Random splotches.

The toner cartridge waste bin overfilling and it dumping toner back on the OPC unit (then transferring it to your document) can also cause this. To solve this problem you will need to get another toner cartridge in your machine as soon as possible. Normally, anything on the front of the paper is a cartridge problem, anything on the back of the paper is a printer problem. The exception would be if the fuser roller cover was damaged in some way.

Squeaking sound.

Squeaking sounds mostly come from the printer, not the toner cartridge. Check this by putting in a fresh toner cartridge. If the sound still persists then contact a local remanufacturer, or printer repair shop to fix your printer. If the sound goes away, then it’s your toner cartridge and it probably has come to the end of its life and needs a major overhaul.

Toner spills.

Toner Spills can be caused from many things. Excessive handling in transport or defective toner seal and recovery blade are common reason for this problem. We test every remanufactured toner cartridge before we send it out at Laser Excellence! But still accidents do happen that is why we have a unconditional guarantee on all our remanufactured toner cartridges.

Variable Print Density.

Variable print density is a common sign that your toner cartridge is coming to the end of its natural life and should be replaced. Usually you can take the toner cartridge out of the machine and gently shake it forward and backwards to redistribute the remaining toner in the cartridge. This usually will give you a few more prints, but you should replace that toner cartridge as soon as possible so not to cause damage to your printer.
