banding lines are generated by the software when the application incorrectly interprets
the media advancing/ink firing sequence of the expected print file or when text an error
occurs within the host application. Errors can also be caused by insufficient host
workstation or RIP memory or processing power. Because it is not directly tied to a
mechanical movement, the bands become inconsistent in both frequency and duration.
The possible causes are the printer driver, the original software package, or the RIP, if
one is used. To eliminate the chance that it is the printer driver:
1) Remove any RIP or network systems and connect the printer directly to the
computer via the printers parallel port.
2) Print a test file approved by ENCAD that uses only the ENCAD print file utility
version 3.0 (EFPU 3.0) and the ENCAD printer. Send a test file via LPT1 with
ECP mode enabled with DMA channel assignment.
If the test file prints correctly, the problem lies in either the software package that
generated the print or the RIP, if used. The problem could also be with the built-in E-
Connect print server or with the workstation transmitting the print data directly to the
printer’s parallel port. To eliminate the E-Connect print the Semi-Circular Nook test
pattern by quickly depressing the TEST button at right rear of printer (Ensure the short
(15”/39 cm) parallel printer cable is attached between parallel ports prior to activating
the test.
A simple test to determine if the banding is caused by the computer/RIP/application or
the printer is to rotate the image 90 degrees and see if the banding rotates or remains in
the same orientation as the previous print. If the banding does not rotate, then look for
causes in the printer. If the banding does rotate with the image, then look for causes in
the computer/RIP or application.
