Print job is extremely slow.

Cause

Solution

You are printing a PDF or PostScript (PS) file but are using a

PCL device driver.

Try using the PS device driver rather than the PCL device

driver. (You can usually do this from a software program.)

In the device driver,

print jobs

NOTE

If you change the setting to plain paper, the

print job will print faster. However, if you are using

heavy media, for best results leave the device driver

set to heavy even though printing might be slower.

Print job prints on both sides of the paper.

Cause

Solution

The device is set for duplexing.

See

Open the printer drivers

to change the setting, or see the

online Help.

Print job contains only one page but the device processes the back side of the page as well (the page comes part of

the way out, and then goes back into the device).

Cause

Solution

The device is set for duplexing. Even if the print job contains

only one page, the device also processes the back side.

See

Open the printer drivers

to change the setting, or see the

online Help.

Pages print, but are totally blank.

Cause

Solution

The sealing tape might still be on the print cartridge.

Remove the print cartridge and pull out the sealing tape.

Reinstall the print cartridge.

The file might have blank pages.

Check the file to make sure that it does not contain blank

pages.

The device prints, but the text is wrong, garbled, or incomplete.

Cause

Solution

The device cable is loose or defective.

Disconnect the device cable and reconnect it. Try a print job

that you know works. If possible, attach the cable and device

to another computer and try a print job that you know works.

Finally, try a new cable.

The device is on a network or sharing device and is not

receiving a clear signal.

Disconnect the device from the network and use USB cable to

attach it directly to a computer. Print a job that you know works.
