Defective Images When Printing on Envelopes

Defective images like the one shown below can occur when printing on envelopes.

• [A] Image distortion due to uneven texture at paper edges (sides, trailing edge)
• [B] Poor fusing when printing more than three envelopes consecutively
• [C] Poor transfer at envelope creases

Cause

[A] Image distortion due to uneven texture at paper edges (sides, trailing edge)

[B] Poor fusing when printing more than three envelopes consecutively

[C] Poor transfer at envelope creases

Action

Apply any one of the countermeasures.

[A] Distorted image

• • Narrow the print area of the image by increasing the white space (margins) at sides and trailing edge.
  • Do not print halftones and filled areas near the edges of the image.
  • Change the type of envelope.

[B] Insufficient fusing

• • Change to envelopes of other types of paper with fusing temperatures: Envelope 2 (205°C), Envelope 3 (210°C).
  • Raise the fusing temperature for the envelopes.

[C] Poor image transfer

• • Position the image print area away from creases.
  • Switch to envelopes made by another manufacturer.
