Parameters Printed Below EEROM Text Block (Decimal Values)

Number of Power Cycles Number of times plotter has been switched on.

Number of Pages Printed

Number of Bail Lifts

Number of Bail Errors

Number of System Errors

Last System Error

See System Errors earlier in this chapter for correspondence of numbers to errors.

Last System Error Data

Bail Up Position Offset Calculated during bail calibration.

Bench Run Whether the bench run has been performed or not.

Bench Run Maximum YĆAxis PWM YĆaxis = carriage axis.

Bench Run Maximum XĆAxis PWM XĆaxis = media axis.

Encoder Tests Maximum YĆAxis PWM

Encoder Tests Maximum XĆAxis PWM

Last XĆAxis Calibration XĆaxis calibration = accuracy calibration

Factory Calibration Factor

This is the driveĆroller correction factor, calculated during accuracy calibration.

Setup Sheet LED Calibration formula.

The values in the formula are calculated during the setupĆsheet calibration.

Reading the EEROM Text Block

The contents of the EEROM integrated circuit are printed in hexadecimal form in a text

block on the service configuration plot.

To read the EEROM text block, perform the following procedure:

, Examine the EEROM memory map in Table 8Ć1 to find the memory address of the data

you want to read.

. Use the memory location key in Table 8Ć2 to locate the position of the memory address on

the service configuration plot.

A Read the contents of the memory address from the service configuration plot.

Example: Searching for the mediaĆsensor correction factor

1 The EEROM memory map Table 8Ć1 indicates that the memory address of the

mediaĆsensor correction factor is 1b.

2 The memory location key Table 8Ć2 indicates that address 1b is located in the second row

from the top, in the fifth column from the right.

3 On the sample EEROM text block Table 8Ć3, address 1b contains the number 0.

Therefore, in this case, the mediaĆsensor correction factor is hexadecimal 0 = decimal 0.
