00

Value=55 if EEROM has been initialized

(Read by servo processor)

01

Value=AA if EEROM has been initialized

(Read by servo processor)

02

Value=5A if EEROM has been initialized

(Read by servo processor)

10

Byte 0 of the number of bench-run cycles completed

11

Byte 1 of the number of bench-run cycles completed

15

Number of stepper cycles per bench-run cycle

16

Byte 0 of the total number of bench-run cycles

17

Byte 1 of the total number of bench-run cycles

18

Number of waits per bench-run cycle

 

19

Number of bail cycles per print in bench run

1a

Number of swaths per bench-run cycle

 

1b

Media-sensor correction factor. (Calculated during media-sensor calibration)

33 (bit 6)

Bit 1 (MSB) of bail-calibration (00 = not calibrated; 11 = calibrated;

 

status..

01 and 10 = calibration in process)

33 (bit 7)

Bit 0 (LSB) of bail-calibration status.

 

36 (bit 7)

Need-cartridge-alignment flag. (1 = needs cartridge alignment)

37 (bit 0)

Valid-cartridge-alignment flag. (1 = alignment performed OK)

39

PWM for carriage LED (calculated during cartridge alignment)

3d

Byte 1 of media-axis alignment distance. (Positions engagement lever.)

3e

Byte 0 of media-axis alignment distance.

 

 

Constants at address locations 3F through 4D are loaded

 

when the cartridge-alignment routine is performed.

3f

Value used to correct position of carriage LED relative to media axis.

40

Value used to correct position of carriage LED relative to carriage axis.

41

Cartridge offset. (Used to correct distance between the two cartridges.)

42

Bi-directional offset in columns. (Used to compensate for differences between ink-drop

 

trajectory when carriage is moving from left to right and that when carriage is moving

 

from right to left.)

 

 

4b

High-velocity factor, scaled by 64. (Used to adjust the bidirectional offset when the plot

 

quality is set to draft mode.)

 

 

4d

Cartridges' first nozzles (Not all of the nozzles are used; there may be an overlap

 

between the two cartridges to allow for alignment. Bits 0 and 1 indicate the first nozzle

 

used on the right cartridge. Bits 2 and 3 indicate the first nozzle used on the left

 

cartridge.)

 

 

4e

Drive-roller correction factor. (Calculated during accuracy calibration.)
