6.7 Adjusting the Media Feed Roller Balance
If the media is inclined to meander at the media feed-in to one side, media feed roller balance
adjustment may be required.
This media feed roller is spring loaded on each end and embedded in the media sensor assembly. By
adjusting the screw on either end downward, the pressure on that end is increased. Likewise, an
adjustment of the screw upward on either end, reduces pressure on that side.
Before adjusting the media feed roller, ensure the print head is properly positioned and balanced.
Required tools:
Phillips screwdriver
Long-nose pliers or wrench
The adjustment procedure for the media feed roller balance is as follows:
1 Open the top cover of the product.
2 Locate two screws  on the top of the
feed roller and media sensor
assembly .
3 Loosen the locknut  underneath the
screw  on either side.
4 Adjust the relative screw  to increase or
decrease the pressure.
• Tighten the screw to increase the pressure.
• Loosen the screw to decrease the pressure.
5 Perform media feed to check the flow of the
media.
The media must not meander.
6 Adjust the same screw  in step 4 again until the media feed without meandering.
7 When the desired outcome is achieved, hold the adjusted screw  in position while
tightening the relative locknut .
