HP Network ScanJet 6 = HP Digital Sender 9100C Upgrade & Conversion

http://berklix.com/scanjet/scanjet6.html by: Julian Stacey

Software & Hardware upgrades to FreeBSD (& Linux)

This page supplements main Page on HP Network ScanJet 5

Upgrade your multi sheet feed scanner software Free,
or purchase a conversion.

The HP Network ScanJet 6 was relabelled as HP Digital Sender 9100C. It looks just like the HP Network ScanJet 5 I convert/upgrade for customers, except the HP Network ScanJet 6 / HP 9100C Digital Sender 9100C has a fuller keyboard than the HP Network ScanJet 5.

I offer a tentative a commercial conversion/ upgrade service as they look similar, & I've done numerous HP Network ScanJet 5s for customers before.

Photos Inside, received from Scott B. 9th Aug 2007

As I haven't had the chance to physically examine an HP Network ScanJet 6 / HP 9100C Digital Sender 9100C inside yet, I might (or might not) need the actual whole machine for the first one, in case anything else is different. Shipping the whole machine would necessitate you finding good packing. & higher freight charges, but with a few good photos from a digital camera emailed to me, maybe I can do the job as per a HP Network ScanJet 5, just sending discs, ethernet & ram (& lot lighter, less fragile, & less trouble than a scanner)

RAM

HP's Product spec says "B/W document, color document, B/W or color photo" It may need a lot more memory than the HP Network ScanJet 5 which can get away with just an 8M plug in during upgrade (then again, the HP Network ScanJet 6 / HP 9100C Digital Sender 9100C may come new originally configured with enough memory for colour scanning at maximum (but what?) resolution & colour depth.

Picture dscn1637.jpg show 4 chips number 48LC2M8A1.

  • idhw.com list this chip as
    • MT - Micron Technology,
    • 48 - SDRAM sync,
    • L - 3.3V,
    • C - CMOS,
    • 2M8 - 2MBit x 8,
    • A1 - 4K refresh - Fast Page
      • So that's 8 M byte.
        No chips on other side of module as shown by dscn1639.jpg
        No space on board for more than one memory module as right of hp9100c/dscn1634.jpg shows no space for a 2nd slot.
  • So memory module is 8M : uncomfortably tight, depending on kernel size, might not run, too small for scanning colour .


Ethernet

It can come with any of 10Base-T (C1313A),Token Ring (C1315A),10/100Base-T (C1316A),10Base-T/10Base-2

Colour

[10Base-T/10Base-2 ?]Spec says colour scanner

Nice - but that needs more memory & different parameters to scanner software.
  • 600 dpi (dots per inch)
  • 15 pages per minute (text quality)
  • 40-key alphabetic keypad
  • 12-key numeric keypad
Questions:
  • Which CPU ? (upward from 486 to 586 perhaps )
  • Which bus (upward from ISA to PCI perhaps ?
  • IRQ: unknown if more/less weidities than mis-placed scsi irq as on Network ScanJet 5
  • Need to check my .rar for eg IRQ hints
  • Not known what differences in control on extended keyboard compared to Network ScanJet 5
  • Not known what differences in control on extended LCD screen compared to Network ScanJet 5
  • Colour : Trevor B. reckons that's what the C at end of 9100C stands for. Need to calculate implications on memory for scan buffer etc & parameters.
HP quote from web
"No replacement product is available for this discontinued product" HP quote from Admin guide pdf "Network servers are needed only to connect LAN fax and other programs. No network servers are needed to support the remaining features.
"The following client operating systems are supported: Windows NT 4.0 and 5.0 workstation and server (TCP/IP only)
Windows 9x (TCP/IP only)
The HP 9100C Digital Sender works correctly with the Microsoft TCP/IP protocol provided as part of these operating systems."
