In all other respects, the two printers are electronically, mechanically, and operationally the same. Note in Sections 1.2, and 9.12. · The front power-on switch and indicator are removed ------------------------------------------------------------ from the front panel of the PrintServer 17/600 printer. · The PrintServer 17/600 printer logo snaps into the front panel hole ------------------------------------------------------------ where the power switch was. The logo covers the indicator light holes and the switch icon. · The PrintServer 17/600 printer prints at 400 and 600 dots per inch (dpi) for high-quality graphics and letter quality text. · The PrintServer 17/600 printer supports PostScript Level 2. · The PrintServer 17/600 printer 's higher dot density is made possible by the following five redesigned field replaceable units (FRUs). See Section 2.6 for the new part numbers. - Scanning unit - DC controller board - High-voltage power supply assembly - Low-voltage power supply assembly - AC drive board · New version V2.1 controller board firmware supports the PrintServer 17/600 features and the existing PrintServer 17 features. See Section 2.2 for more information. PrintServer 17/600 2-1 2.1 Differences 2.1.1 Redesigned Components The following FRUs have been redesigned for improved operation or reduced cost: Note in Sections 9.7, 9.7.1, 9.8, and 9.15. · The new controller board, which resides under the printer, replaces the original controller board (backward compatibility) and operates both the PrintServer 17 and PrintServer 17/600 dpi printers. There are some minor sheet metal differences ------------------------------------------------------------ between the original and the new controller boards. · The new non-parity SIMMs support controller board firmware V2.1 or higher. See Sections 2.4 and 2.6.1 for additional information. 2.2 Firmware Differences To date, the following versions of PrintServer 17 controller board firmware have been released. Table 2-1 Firmware Code Differences ------------------------------------------------------------ V1.0 Supports 300 dpi PrintServer 17 printers only. V1.1 Supports 300 dpi only. Fixed a bug that caused potential ?54 errors during IP booting. Improved error coding for field test mode (FTM) errors. See Section 6.16 in the PrintServer 17 Printer Service Guide. Add information to Section 7.1.1 V2.1 ------------------------------------------------------------ Supports 300, 400, and 600 dpi PrintServer 17 and PrintServer 17/600 printers. Added a cost-reduced controller that features non-parity memory and improved network booting. ------------------------------------------------------------ Note: There is no implied mandatory reason to upgrade or change the older firmware. If a controller board that is operating under V1.x firmware goes bad, you can replace the defective board with a new board that has V2.1 firmware. 2-2 PrintServer 17/600 2.3 New Boot Error Code 2.3 New Boot Error Code The boot errors in Table 2-2 are caused by a misconfigured host or boot server or by a malfunctioning network. Table 2-2 Boot Errors Append Sections 2.3, 5.6 and 6.3. ------------------------------------------------------------ Message Explanation ------------------------------------------------------------ Ethernet address ?55 ------------------------------------------------------------ An illegal or unknown file was downline loaded from a ------------------------------------------------------------ volunteer that responded to the boot request (BOOTP) ------------------------------------------------------------ . Ethernet address ?56 (nn) ------------------------------------------------------------ This error information is useful for troubleshooting network or system software. nn shows one of the following trivial file transfer protocol (TFTP) errors: 01 = Rear request (RRQ) ------------------------------------------------------------ 02 = Write request (WRQ) ------------------------------------------------------------ 03 = Data error (DATA) ------------------------------------------------------------ 04 = Acknowledgment (ACK) ------------------------------------------------------------ 05 = Error (ERROR) ------------------------------------------------------------ ------------------------------------------------------------ PrintServer 17/600 2-3 2.4 New Non-parity SIMMs 2.4 New Non-parity SIMMs Non-parity memory SIMMs replace the original parity SIMMs on the controller board. The older parity SIMMs work under all versions of the controller board firmware. Append 6.1, 6.1.1, and 9.15 Installing non-parity SIMMs with V1.0 or V1.1 causes the power up bootstrap to hang at the 9, 8, or 9, 7 ------------------------------------------------------------ point in the countdown. (For a description of the power up bootstrap, read chapter 2 of the service guide.) Install only non-parity SIMMs with version 2.1 or higher controller board ------------------------------------------------------------ firmware. ------------------------------------------------------------ Note: See chapter 2 of the service guide for a description of the bootstrap process. 2.4.1 New SIMM Configuration Minimums The following lists the minimum memory requirements for the various PrintServer 17 configurations: · 12 MB for a simplex or duplex PrintServer 17 printer · 16 MB for a level 2 PostScript, simplex or duplex PrintServer 17/600 · 20 MB for legal size duplex printing on the PrintServer 17/600 2-4 PrintServer 17/600 2.5 New V2.1 FTM Test Patterns 2.5 New V2.1 FTM Test Patterns Figure 2-1 shows the 400 and 600 dpi test patterns that are printed by a PrintServer 17/600 printer. An example of the PrintServer 17 300 dpi pattern appears in Figure 4-2 of the service guide. Note under Figure 4-2. · Patterns A and B are printed at 400 dpi. Compare the B and D test test patterns. Notice how the B pattern is smaller on the page then ------------------------------------------------------------ pattern D. This only happens at 400 dpi. ------------------------------------------------------------ · Patterns C and D are printed at 600 dpi. Compare the C and the A test patterns. Notice how the C test pattern is horizontally compressed. ------------------------------------------------------------ This compression effect increases as the density (dots-per-inch) increases. ------------------------------------------------------------ Figure 2-1 New V2.1 Controller Board Test Patterns Ray MacDonald:Leo-lps17-600:Leoltr-b.epsDSG-000779ðTX ------------------------------------------------------------ New Gradient 1 ------------------------------------------------------------ New Gradient 1 ------------------------------------------------------------ Ray MacDonald:Leo-lps17-600:Leoltr-3.EPSRay MacDonald:Leo-lps17-600:Leoltr-4.EPSPattern AðTX Pattern CðTX Pattern BðTX Pattern BðTX Pattern DðTX 2.6 New Field Replaceable Units 2.6 New Field Replaceable Units Table 2-3 lists printer-specific FRUs.
