DFX-5000+ Service Manual Adjustment 4.1.6 Platen Angle Adjustment (Right Angle) This section describes the platen angle adjustment. The platen must beat a right (90° ) angle to the carriage assembly. This adjustment is required when the platen is removed or replaced or when the 2 hexagonal screws securing the platen to both side frames are loosened. Do not remove the printer mechanism from the lower case. (If remove the printer mechanism from the lower case, the adjust value will be out of order when you reassemble the printer mechanism to the lower case.) Also, it is necessary to remove the tension roller shaft be fore performing this adjustment. (Refer to Section 3.2.7.7) The parallelism is adjusted so that the difference between the distances (from the rear carriage guide shafi to the platen measured at the two positions shown in Figure 4-7) is less than 0.01 mm. Since this value is extremely small, you must use the 2 dial gauges, dial gauge base, and dial gauge master supplied by Epson. Do not adjust the parallelism using any other method.

4.1.6
Platen Angle Adjustment (Right Angle)
This section describes the platen angle adjustment. The platen must beat
a right (90° ) angle to the
carriage assembly. This adjustment is required when the platen is removed or replaced or when the
2 hexagonal screws securing the platen to both side frames are loosened.
Do
not remove the printer
mechanism from the lower case. (If remove the printer mechanism from the lower case, the adjust
value will be out of order when
you
reassemble the printer mechanism to the lower case.) Also, it
is necessary to remove the tension roller shaft be fore performing this adjustment. (Refer to Section
3.2.7.7)
The parallelism is adjusted so that the difference between the distances (from the rear carriage
guide
shafi
to the platen measured at the two positions shown in Figure
4-7)
is less than 0.01
mm. Since this value is extremely small, you must use the 2 dial gauges, dial gauge base, and
dial gauge master supplied by Epson. Do not adjust the parallelism using any other method.
