Laser printers do not use a printhead. When the toner runs out you need to get a new toner cartridge which includes the print drum. You lift up the cover to reveal the toner cartridge, grab the cartridge and pull it out towards the front of the printer. Reverse this procedure to insert the new toner cartridge.
This means your ink level is low but you can confirm this by doing the following;
.The Lexmark C500n uses powdered ink, called toner, like other laser printers. The printer creates a magnetic charge on the paper as it passes through the machine, forming text and images on the page. The printer then applies pressure and heat to the paper, fusing the powdered ink to the page so it will not smudge or run. At any time, you can check the amount of ink left in the printer's toner cartridge by printing a status page. This page will also show a tally of the number of pages printed by the machine, among other information.
Turn on the printer and let it warm up. Ensure the light next to "Ready" illuminates.
Press the "Go" button, or the button with the icon of the hand pressing a button. Use the arrow button on the printer's control panel to highlight "Test Menu," then press the button with the check mark.
Press the arrow button until you highlight "Status Page" on the printer's display panel. Wait as the printer generates a status page.
Retrieve the status page from the printer's output tray.
By doing this you will know the level of your toner.
Print quality issues can be due to a number of things. There may be a defect in the cyan toner cartridge causing it to leak excess toner. The transfer belt could be dirty or defective. The printer may simply need cleaning. Given that you posted this question during the winter, it's also very likely a low-humidity environment is causing a high-static condition, randomly pulling extra toner onto the page.
The easiest thing to do is clean the printer. Take a vacuum with a small attachment and clean out any excess toner. If you have canned air or a vacuum with a blower you should also blow out toner from any crevices that may not be reachable with the standard vacuum.
If you have a spare cyan toner, you can try installing that and printing a series of test pages. The built-in demo pages are good as they will use a fair amount of toner and should help gauge if this solution helps.
The transfer belt is the most expensive component to replace in the printer. If it needs replacement you will have to contact an authorized HP service company. However, before doing that, you should try the above steps and run a few iterations of the built-in cleaning process. You can navigate the printer's menus to find this function.
Many people over-look low-humidity and static conditions, or do not believe they could have an effect on laser printers. However, static charge is the very principle on which laser printers work and is how the toner is transferred to and held on the page before it is run through the fuser. Low humidity can easily cause dirty printouts. Try placing a ream of paper in a more humid area for a couple days, then load the printer with that paper and print several test pages. You can also try placing a humidifier near the printer and leave it running for several days and try printing test pages again. If this solves the issue, maintain a humidifier in the proximity of the printer for the duration of the season until the weather warms up and the average humidity increases.
Press the Go and Rotate Carousel buttons simultaneously. This will calibrate the printer. See if this works.
Otherwise....Remove all cartridges and drum. Switch off printer. Close the lid. Switch on printer and wait until any churning stops. Insert the drum and close the lid. Wait until any churning stops. Put in one cartridge at a time, closing the lid and wait till it stops churning each time. With the last cartridge put in, it will churning longer (calibrating). Try to print from your computer.
It could also be that the toner could actually have run out for the other colors.
1 Could be toner on the contacts (inside the printer) that mate with the contacts on the cartrdige.
2 Are you sure they are 510 toners and not 500 ones ?? 510 toners have a chip that identifies the cartridge (Colour, Capacity) and maintains a count of the pages printed.
500 toners have a reset fuse that resets the toner counter in the printer, and a resitor that identifies the capacity
3 Are they new cartridges, remanufactured, or 'home refiled'.
if either of the later two, were the chips replaced ? - if not the cartridge still thinks it has printed its full life of pages.
