Instructions For Printer Cleanup The following setting will clear up a lot of problems that you may run into while printing with the 4500 and 4550 full color laser printers. The 4500 and 4550 are very high end printers and you have a variety of functions that you can use to clear up time to time printing problems. The problem generally comes from using papers such as general purpose and copy type paper. The fact is all papers are not created equal. General purpose paper and copy papers are all 20 pound, non conductive papers. This means these papers do not carry a charge. Laser printer papers are all 24 pound paper and they all have conductivity. This means that they carry a charge. When printing with a laser printer paper this means that when you are printing multiple prints, the paper is helping to keep the charge up in the printer. General purpose and copy papers take a charge out of your printer as you print. This can result in washed out and or light prints. Papers that say they can also be used in ink jet printers contain an added chemical that equates to moisture in your paper. These chemicals are needed in ink jet paper to get the liquid from the ink jet paper to stick to the paper. Unlike your laser, the ink jet does not use heat to fuse the product to the paper. General purpose and copy paper are also very course and rough. Your paper comes in direct contact with the drum unit in your printer. The rougher the paper the faster your drum unit will wear down, sometimes causing the drum unit to go out or need to be replaced sooner than normal.

You may use what ever you feel comfortable with, this is just information that we feel can help when you need it
