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.
