[Procedure 2]
This procedure should only be used when the proper pressure cannot be
achieved with procedure 1.
1. Remove the plotter unit.
2. Set the lever for adjusting the paper feed roller pressure up.
3. Remove the right front cover, main PCB, and image processing PCB.
4. Manually rotate the paper table drive gear to raise the paper table to the
paper feed position. (Paper table height sensor is interrupted.)
5. Align the lower adjusting plate notch with the center notch of the link [C]
and tighten the screw [B].
6. Hook a tension gauge (500-gram range) to the paper feed roller shaft [E].
Insert a strip of paper [D] between the paper feed roller and the sheets of
paper. Then hook a tension gauge (100-gram range) to the paper strip
and apply a 100-gram load. Now gradually pull up the tension gauge
hooked to the shaft and make sure that the paper strip can be pulled out
when the tension gauge shows 250
±
5 grams.
7. If this is not the case, adjust the pressure by moving the mounting
position of the shaft [A].
