4.4.1 Scope
This specification describes the hardware and firmware changes required to obtain paper out and jam status
information from the parallel port of the SP-5000 printer.
4.4.2 Description of Status Signals
Paper Out and Summary Jam Status information is available at the I/O pins of the parallel port as shown in the
following table:
Signal Name PE SLCT /Error Printer Status
Pin No. 12 13 15
Signal Levels: Low High High Ready to Receive Data
Low Low Low Printer Jam
High Low Low Out of Paper
A paper jam may be detected at either one of two different locations in the printer. The locations are in the cutter
and in the delivery system. The printer will indicate the location of a jam by issuing different audible warning alarms
for each location. The summary status sent to the parallel port indicates that a jam condition exists in the printer
but it does not signal the location.
4.4.3 Description of Changes Required
4.4.3.1 Hardware Changes
The following hardware change is required on the SP-5000 Rev. D4 Controller Board:
·
Make an etch cut at P2 pin12 (solder side of controller board).
·
Add a jumper from P2 pin 12 to U4 pin 5.
·
Add a jumper from RP7 pin 8 to RP7 pins 2 and 3.
4.4.3.2 Firmware Changes
Firmware Revision D4-01 or higher is required.
4.5 Parallel Interface Cable
This parallel cable configuration is used to interface the SP-5000 with all IBM and IBM compatible systems. This
cable connects the interface to the printer with a 1:1 cable connection, and is terminated by a DB-25P on each
end. This 25 pin cable configuration is available at most computer supply stores. ex. pin 1 to pin 1, pin 2 to pin
2,...pin 25 to pin 25.
Please Note:
Cable length for the standard mode of parallel printing (through MS-DOS) should be limited to 25
feet or less.
When printing through Microsoft Windows® in the
fast printing to port
mode,
cable length must be limited to 6
feet or less
. In this mode of print, the standard MS-DOS machine interrupts are not used for printing, which
regulates data flow to the printers parallel port. In this printing mode, Centronics Standards for timing data flows
are not utilized. Telpar suggests that during the printer set up in Microsoft Windows® the fast printing to port option
be de-selected.
4.6 Optional Microsoft Windows® Driver Diskettes
Telpar offers optional Microsoft Windows® driver diskettes for use with Microsoft Windows® applications.
4.6.1 Telpar SP-5000/2 Windows Driver Disk
Since the SP-5000/2 has a 2.35 inch wide print area, three Windows print drivers are provided which should allow
for all printing requirements.
