3.1.2 Items to be Confirmed Before Going to Image Quality Troubleshooting

Image Quality Problems
Taking firm steps to clarify image quality problems (streaks, color deterioration, and blanks) is required as one
of the support items for an end user. To determine the cause of the print problem faced by the end user, first,
confirm the following items to grasp the status of use by the end user.
1 Is the paper matched with the Print Media Guidelines?
2 Is the remaining amount of the toner sufficient?
3 Has the printer been cleaned up lately?
Confirm the Printer Status
Toner
When the remaining amount of the toner is low, image quality problems such as faint print, streaks,
white lines, and blanks) occur. Ask the end user to print the lower-capacity document using a different
application, confirm the problem repeatability, and then check that the remaining amount of the toner is
sufficient for printing. When a document is printed by an end user, the dialog box indicating the remain-
ing amount of the toner appears on the laser printer status monitor.
When the remaining amount of the toner is low, the end user can extend the life of the toner cartridge
slightly by removing the cartridge from the printer, shaking it right and left slowly (this softens the firm
toner), and reinstalling the cartridge.
Cleaning
Image quality problems such as smears and toner spots might occur when particles of paper, toner, or
dust is piled up in the printer. Cleaning the inside of the printer can prevent the problems.
