Memory information

The HP Designjet 650C printer has 4 megabytes (MB) of standard on-board RAM. A PostScript ROM SIMM and MIO card are optional. There are two RAM expansion slots which can hold optional 2 MB, 4 MB, 8 MB, 16 MB or 32 MB single in-line memory modules (SIMMs). The maximum expandable RAM is 64 MB additional, or a total of 68 MB. (Before the introduction of the Model B printer and the 16 and 32 MB SIMMs, maximum expandable memory for the Model A printer was 20 MB as specified in the User'sGuide.)
The HP Designjet 650C/PS printer comes pre-installed with 4 MB of standard on board RAM, a PostScript ROM SIMM and Jetdirect MIO card and requires a minimum of 4 MB additional memory or a total of 8 MB.


"Normal" printer use

"Normal" printer use means less than:
  • 40 pages per day (if medium-density E/A0 CAD plots), or
  • 10 pages per day (if medium-density E/A0 image prints)
The reliability of the HP Designjet 650C printer will be maximized by maintaining an output volume within 40 EA0-size plots per day on average. The HP Designjet 650C printer can support the occasional need for up to 100 plots per day, but the regular use of the HP Designjet 650C printer above an average of 40 plots per day may result in increased maintenance requirements.
Producing more than 40 E/A0-size plots per day and/or changing the most frequently used pen cartridge (generally the black) more than once every 3.5 days, is working the HP Designjet 650C printer at above average conditions which will result in increased maintenance requirements.
A plot counter is contained in the EEROM of the printer, the contents of which can be seen by performing a Configuration Plot from the front panel. For all 'A' models and 'B' models below firmware rev. 5.11 the plot counter only reflects non-PostScript plots. For 'B' models starting with firmware rev. 5.11, both PostScript and non-PostScript files are counted. The value is listed in hexidecimal format on line 0 of the EEROM map at the bottom of the Configuration plot, in columns c, d, and e. The count is displayed in reverse order and must be reversed when determining the number of plots.

To print the configuration plot

  1. Make sure media is loaded.
  2. In the Full Menu mode, choose Utilities.
  3. Choose Config Plot option and press ENTER.
