Technical Bulletin
If you are experiencing y-axis registration problems, check the following:
1. Worn or loose y-axes drive belt. You can measure the y belt tension by moving
the carriage all the way to the right end plate. The y belt should be firm and taut,
but not stretched. Using a spring force gauge, measure the belt tension from the
center of the machine, by deflecting the belt from its natural position
approximately 1/8 inch with 180-220 grams of force applied.
2. Worn or loose y-axis transmission timing belt.
3. Loose or worn pulley on y-axis transmission. Check all pulley set screws.
4. Pen is seated properly into the pen flange.
5. Loose pen jaw.
