NovaJet 800 Series Service Manual

Suggest increasing memory to 256 MB for low pass print mode opera- tions. Typically this only affects CAD (computer aided design) users that send HP-GL/2 files (vector) to the printer. File format examples include

.plt and hp2.

Miscellaneous Notes

Note: NT does not support ECP parallel port mode, an additional parallel port (PCI card) must be installed or a configuration with a network and print server is suggested. Also turn off the Video ROM shadow in the BIOS as this can cause a 20% overhead on the CPU. Verify the Win- dows Screen Saver is always turned off as this may cause hesitation as well. Another tip is to RIP to disk or print to file and then send the file via the EFPU3.0 (ENCAD File Print Utility version 3.0) to see if this elimi- nates the hesitation. For hesitation associated with only vector files, such as plot or hp2 files, the problem could be insufficient memory. Increase printer memory from 64MB to 256MB.

To prove printer performance select the Pause feature, and wait 20 to 30 seconds before de-selecting Pause. If printer is working properly the carriage head should stop hesitating and production performance should increase for a short period of time.

Network Connectivity

The printer comes with a built-in 100BaseT network board which inter- faces via two cables, an SEH server, or an onboard, built-in Ethernet port. If you are using the E-Connect (NJ850 only, then attach the provided parallel printer cable (15”/39 cm) between the upper centronics parallel port and the lower parallel port at right rear of printer. Attach an Ethernet cable to the E-connect jack. Verify the green LED (OK) illuminates. The green LED (OK) indicates the server is communicating with the network.

The white LED (TEST) should illuminate (amber in color) briefly only at power up and then extinguish. The yellow LED (100) indicates a 100baseT network exists and is online. E-Connect supports high speed ECP (enhanced capabilities port) parallel port mode with DMA (dynamic memory access) and Bi-directional data transfer up to 1 Megabytes per second. A short (15" or 39 cm) IEEE 1284 compliant parallel cable must
