General Troubleshooting

Problem

Probable cause

Solution

Prints curl.

On some paper types, prints with uneven coverage

When making prints with heavy coverage, select

 

may curl where coverage is heaviest.

Face Down as the Output Order at the printer’s

 

 

front panel or from your application’s Print menu.

 

 

 

Oversize media does not feed from the universal paper trays or the multi-purpose tray.

Too much media is loaded in the tray.

Decrease the amount of media loaded in the multi- purpose tray. See “Specialty Media” on page 14 for the tray capacity for different types of media.

Toner residue is found in the printer.

Toner cartridges are being removed and reinstalled in the printer before they are empty.

Remove toner cartridges only when they are empty and you have been prompted by the front panel to replace them.

Media frequently wraps around the fuser.

Incorrect media is being used.

■ Use laser paper only; do not use inkjet paper.

 

 

■ Use only Tektronix Glossy Coated Paper.

 

 

■ Make sure that transparencies are loaded with

 

 

the notch in the correct position. See “Loading

 

 

the Optional Transparency Tray” on page 13 and

 

 

“Transparencies” on page 15.

 

 

 

 

The fuser roll cartridge is used up.

Replace the fuser roll cartridge.

 

 

 

Colors printed are not accurate.

An incorrect color correction is being used.

■ Select a different color correction. See page 23

 

 

for more information.

 

 

■ Open and close the front door of the printer. This

 

 

action causes the printer to autocalibrate the

 

 

colors.
