Macintosh printing problems

6-22 Phaser 300i and 300RX Color Printer
10. An electrical failure in the umbilical cable between the carriage board
and the print engine control board can cause a single jet to consistently
fail.
11.
As explained in the Chapter 9 topic "Printhead maintenance and test
printing" on page 9-7, enter service mode's Maintenance menu and
run of series of low and high purges on the affected jets. Run a low
purge for 30 seconds and then quickly run a high purge for 30
seconds. Repeat this sequence for 2 to 3 minutes.
12. Increase the printhead voltages to their maximum as explained in
Chapter 9, "Voltage, convergence and temperature adjustment for a
new printhead" on page 9-17 and repeat Step 11 and then make a test
print to see if the jet is cleared.
13. If the problem persists, replace the printhead.

1.
Make sure the correct Phaser 300i icon was selected in the Chooser.
Try printing the job again.
2. In the Chooser, switch background printing to off. Try printing the job
again.
3.
Download the Error Handler utility and try printing the job again.
(Refer to the Chapter 3 topic "Using the Error handler utility.") If an
error page is printed after printing the job again, call the Customer
Support Hotline for further assistance. Please have the error page in
hand.
4. If available, try printing to a black-and-white PostScript printer (such
as an Apple LaserWriter). If the file does not print on the black and
white PostScript printer, this may mean that the problem may be
application- or network-related.
5.
Ensure the print engine can print by pressing the front panel TEST
PRINT switch to print an internal test print.
