Gestetner f250 Operating Guide

A.11

: 

• To avoid damaging the machine, use only labels recommended for laser printers.
• To prevent serious jams, always use the manual feeder to print labels and always use 

the rear output tray.

• Never print on the same sheet of labels more than once and never print on a partial 

sheet of labels.

When selecting labels, consider the quality of each component:

• Adhesives: The adhesive material should be stable at 180°C (356°F), the 

machine’s fusing temperature.

• Arrangement: Only use labels with no exposed backing between them. Labels can 

peel off sheets with spaces between the labels, causing serious jams.

• Curl: Prior to printing, labels must lie flat with no more than 13mm (5in.) of curl in 

any direction.

• Condition: Do not use labels with wrinkles, bubbles or other indications of 

separation.

Transparencies used in the machine must be able to withstand 180°C (356°F), the 
machine’s fusing temperature.

: To avoid damaging the machine, use only transparencies recommended for 

use in laser printers.
