Table 37. Initial troubleshooting checklist

Environment	● Is the printer installed in a suitable environment? See “Site
	requirements” on page 5.
	● Is the printer installed on a solid, level surface?
	● Is the supply voltage (from the wall receptacle) within ± 10
	percent of the printer’s rated voltage (see “Site requirements” on
	page 5)?
	● Is the power cord fully seated into both the printer and the wall
	receptacle?
	● Is the operating environment (for example, the temperature and
	humidity levels) within the specified parameters that are listed in
	chapter 1 (see “Site requirements” on page 5)?
	● Is the printer exposed to ammonia gas, such as that produced
	by diazo copiers or office-cleaning materials?
	● Is the printer exposed to direct sunlight?
Media	● Is suitable media being used in the printer? See “Supported
	sizes and weights of media” on page 10 and “Supported types of
	media” on page 14.
	● Does the customer use only supported print media?
	● Is the media in good condition (no curls, folds, or other flaws)?
	● Is the media stored correctly and within environmental limits?
	● Is the correct side of the page printed on first?
	● Is long-grain paper being used?
Input trays	● Is the correct amount of media loaded in the tray (not stacked
	above the arrows embossed in the tray)?
	● Is the media placed in the tray correctly?
	● Are the paper guides aligned with the paper?
	● Is the tray cassette installed correctly in the printer?
Print cartridge	● Is the print cartridge installed correctly?
Fuser	● Is the fuser installed correctly? See “Fuser” on page 162.
Covers	● Is the top cover closed?
Condensation	● Does condensation occur following a temperature change
	(particularly in winter following cold storage)? If so, wipe off the
	affected parts or leave the printer on for 10 to 20 minutes and
	then attempt to resume printing.
	● Was a print cartridge opened soon after it was moved from a
	cold room to a warm one? If so, allow the print cartridge and the
	printer to acclimate to room temperature for one to two hours.
