Adj Rear Sensor Position - Epson Stylus PRO 7500 Service Manual

EPSON Stylus Pro 7500

ADJ REAR SENSOR POSITION

This function makes sure the P REAR sensor correctly detects the rear edge of cut-sheet
paper to allow the user to print with the largest possible printable area but without printing
off the edge of the paper and marring future printouts. The printer prints an A3-size test
pattern. Using a ruler, measure the distance from the rear edge of the pattern to the rear edge
of the paper, and then enter this measurement when prompted. This value is stored in the
printer's firmware to be referenced against the printhead nozzle position.
1. Make sure "Adj Rear Sensor Pos." appears, and press the Enter button.
2. Load A3-size paper in portrait (short edge first) orientation when you see the "Please
Set CutSheet" message. After the paper initializes, press the Enter button to print the
check pattern.
3. After printing is finished, measure the distance from the rear edge of the printed pattern
to the rear edge of the paper. Press the Enter button until you see "RearSen. Pos.
xx.xmm", and then enter the measurement in increments of 0.1mm using the item
select (Paper Feed) +/- buttons. After entering the measurement, press the Enter button.
4. After input, move to the next adjustment item using the "Enter" button.
