Auto-Status; Sub-Function Adjustment; Agc Position; Platen Gap - Epson MTX 1345 Operator's Manual

- AUTO STATUS (Only indicated if the serial interface is selected)
Possible values: YES or NO
If the Auto Status is set to YES the host is able to check the status of the
printer (for example no paper or printer is in the STOP mode).

- Sub-Function ADJUSTMENT

- AGC Position

AGC (Automatic Gap Control) is an integral part of the paper handling
capabilities of the printer. It is an automatic adjustment function which
ensures an optimal print quality when using various paper thicknesses.
The gap adjustment will automatically take place whenever paper is
inserted
- after the paper source has been changed
- from park position (fanfold)
- after Power On
- after the printer has been in the STOP mode
- an AGC command has been issued.
The reference point for the measurement of the paper thickness is the
AGC Position of the first print line. Default for the horizontal AGC Position
is 24 (= ink ribbon exchange position), any position from 4 to 131 (at 10
cpi) can be selected.
An adjustment of the AGC Position is only necessary if a measurement at
the default position does not reflect the paper thickness of the area to be
printed on or if there is a paper edge (e.g. of a label) in that position (the
measuring process requires a plain paper-surface).
In addition to the automatic AGC function, random measurements of the
paper thickness can be invoked by the AGC command, or a specific platen
gap can be set using the PCC command. This is to meet the requirements
of forms with complex properties. For details see the Programmers Manual
for the printer.

This adjustment is to be seen as a correctional offset to the platen gap set
by the AGC (Automatic Gap Control) function or a PCC (Programmable
Copy Control) command. It effects all paper paths.
The offset is within the range of -3 to +4. One step is equal to 18 µm.
"-" reduces the gap, "+" increases it.
This is a basic adjustment which is automatically performed at the initial
Power On of the printer, and which there after only needs to be initiated
after having exchanged the print head or the platen. It is essential that the
ink ribbon is installed and no paper is in the printer when this procedure is
started. After activating this procedure, the printer displays
INSTALL RIBBON. If the ribbon is installed press
This parameter logically adjusts the base position of the Run-In-Sensor.
The factory set value is such that the default is set to compensate specific
mechanical tolerances. The adjustment range is from -3 to +4 in / " steps
(0.42 mm), where "-" means an upward movement and "+" a downward
movement. When implemented, the adjustment applies to all paper paths.
