Question about HP LaserJet 4200n Printer
What can I clean the rollers with? Can I clean the cartridge? Anything else?
By the way the printer is an HP4200n
Cleaning your rollers will not solve your image problem. Either you have a bad or poorly remanufactured cartridge, or your fuser is bad.
NO TOOLS are necessary to replace the fusing assembly, it is idiot proof---very easy to do. But more expensive than a toner cartridge so try that FIRST.

Tips for a great answer:
Sounds like a fusing error . If your able to wipe the toner off the page its a fuser unit problem (replace fuser unit).
Also clean the copier's paper rollers. Marks on copies will occasionally be the result of a dirty paper-rolling mechanism. Simply access these rollers (your photocopier will likely have a plaque or series of signs indicating the locations of these areas) and wipe them off.
Clean the copier bed's glass plate. One of the most common causes of blemishes in photocopies is a dirty glass plate. In some cases a permanent mark, such as a scratch, will be present on the plate, showing up in every copy as a dark line or spot. However, most problems attributed to the glass plate can be fixed by wiping the plate with a soft towel and common household glass cleaner.
Clear any excess toner that has spilled or overflowed in the toner cartridge chamber. Excess toner will almost always result in blemishes on your copies. The most effective means of cleanup is to remove the toner cartridge and set it aside, thoroughly cleaning up any spilled toner in the compartment before putting the cartridge back in place.
Check for low toner levels. Low toner levels can actually contribute to unsightly lines and blotches on a photocopy. Most photocopiers will automatically indicate the need to replace an empty or low toner cartridge; while the toner is low, these models will permit continued copying. Consult your photocopier's instruction manual or key to warning lights and indicators for how to tell if the toner is low or empty.
