Dump Mode - Canon BJ-W3000 Service Manual

5. Dump mode

This machine is provided with a dump test function to print the input data in hexadecimal and
ASCII code as an online test.
Select "Dump mode" on the system setting menu, and then set the printer online. When data
is transferred from the computer in this state, the data is first printed normally. Then, for the data
received since data reception started until the EOP timer was actuated, the initial 1k byte is
dumped on one A4 sheet, and the last 1k byte is also dumped on an A4 sheet, in hexadecimal
ASCII code.
The printer returns to the normal printing mode automatically after the dump output is com-
pleted. Therefore, to execute a dump again, reselect "Dump mode", and then transfer the file
data.
CAUTION
If data is transferred continuously, the final portion cannot be correctly dumped. To prevent
trouble, transfer only one file at a time in the dump mode.

a. Data size recognition standard
This machine recognizes the size of data received as follows:
(1) PS (Plot size) recognition
Uses the size specified in the PS command contained in the data as the size of the data.
(2) Min./Max. size recognition (coordinates)
Detects the minimum and maximum positions in the range of vector coordinates actually
drawn to determine the data size.
(3) Min./Max. size recognition (line width consideration)
Detects the minimum and maximum positions in the range of coordinate values, including
the vector line width actually drawn.
