3.3.1 Checking the Platen Gap
This section describes the procedure for checking the platen gap (PG).
Tools
Thickness gauge: 1.5 mm (x2), 2.0 mm (x2)
Confirmation procedure
This printer does not have any PG adjustment mechanism, however, it is designed so that the
platen gap can fall within the expected range if you correctly reassemble the unit (including
using the Epson-specified jigs) according to this manual. If the PG cannot fall within the
standard range after performing the platen gap check described in this section, first check if
the unit is correctly reassembled following the instructions in this manual. Even if the unit is
correctly reassembled but the PG still cannot fall within the standard range, replace the unit
with a new/refurbished one.
The standard range of the PG is as follows:
• Standard: 1.95 ± 0.45 mm
When checking the PG, make sure of the following.
Check the PG with new ink cartridges installed to the CR Unit, and also with all parts
related to the PG installed to the printer (p 43).
Move the CR Unit by pulling the CR Timing Belt.
Be careful not to damage the nozzles of the Printhead with the thickness gauge.
