Canon BJC-8500 user manual Problem Printing Blurred, Problem Vertical lines are broken, 127

Problem : Printing Blurred.

If the printed page is blurred, the Ink Optimizer Tank BCI-8WF may be out of ink or you may not be using the correct media for the print job.

1	Print a Nozzle Check Pattern. (☞ 96) If the black pattern on the yellow
	is blotted or blurred, clean the print head and print the Nozzle Check
	Pattern up to five times. If the result is still blotted or blurred, open the
	top cover and visually check the level of the Ink Optimizer. If the Ink
	Optimizer Tank BCI-8WF is out of the Ink Optimizer, replace the tank.
2	If the Nozzle Check Pattern is normal, open the printer driver and
	check the print mode setting and media selection. The ink optimizer
	will operate only with Plain Paper or Envelopes. If Print Quality is set
	for Fast, the ink optimizer will not be used. For details, see your
	Windows Print Guide or Macintosh Print Guide
Problem : Vertical lines are broken.
1	If the vertical lines in your prints are broken or jagged, the print heads
	may be out of alignment. Realign the print heads. (☞ 49)
2	Even after aligning the print heads if lines appear broken, make sure
	the Print Quality is set for Fine. For details, see the Windows Print

Guide or the Macintosh Print Guide.

Problem : Page streaked, faint, or patchy.

Uneven or faint colours can be caused by a clogged print head, an empty ink tank, a worn print head, or printing on the wrong side of the media. Perform the procedure below before you decide to replace the ink tanks or BJ Cartridge. Unless an ink or BJ Cartridge requires replacement, simple head cleaning should solve the problem in most cases.

1	Print a Nozzle Check Pattern and check the results. (☞ 96)
2	Open the top cover and visually check the level of the ink in the tanks.
	If any ink tank is empty, replace it. (☞ 92)
	If no ink tank is empty, clean the print heads and print another Nozzle
	Check Pattern. Alternately clean the print heads and print a Nozzle
	check Pattern until the pattern is normal or stop after printing the fifth
	Nozzle Check Pattern.
3	If the fifth Nozzle Check Pattern is abnormal, execute print head deep
	cleaning. For details, see the Windows Print Guide or the Macintosh Print

Guide.

If the Nozzle Check Pattern is normal, you can resume normal opera- tions.
