Chapter 3 - Theory; Changes From Earlier Models - Pitney Bowes DA80F Service Manual

3.1 Changes
From Earlier
Models
DA80F/DA95F AddressRight™ Printers Service Manual (SV61962 Rev. A)
The DA80F (three print heads) and DA95F (six print heads) are fixed head,
ink jet desktop printers. The DA80F (WF81) and DA95F (WF96) printers are
based on the previous Pitney Bowes fixed head printers (DA400 and DA950,
respectively). For those familiar with the older models, the changes imple-
mented include:
• Updated Main Board, as well as LCD/Keyboard Board/Print Head Driver
Board. Same Main Board used in both DA80F/DA95F models. Now
100% RoHS compliant.
• Elimination of Centronics (parallel) connector; replaced by Ethernet con-
nector (USB port kept)
• Improved paper sensor calibration now accessible via LCD Service menu
• New options on the LCD control panel menus for greater flexibility and
control
• Introduction of a Pitney Bowes "software control panel" (running under
Windows on a separate PC) which mimics the features of the printer's LCD
control panel while also adding more diagnostic and administrative features
• Control panel menu supports bulk cartridge ink management ("low ink"
warning now works when using these types of cartridges)
• Removed large transformer and replaced with heavier duty power supply
(allows a graceful shutdown of the printer and for the software parameters
to be saved). Same supply as used in DA5xx/DA7xx shuttle-head printers.
• Print heads now raise up straight (instead of to the side) which allows
easier access to wipe and clean the print heads
• One printer software for all functionality (uses PB monolithic driver)
• Support for 18 languages in the Operator Guide, soft control panel, and
drivers
DA95F-Specific Improvements
• Removed feeder board (used in predecessor DA950 model)
• New exit sensor and new feeder deck extension
• New "feet" on bottom of feeder allows better alignment of feeder
• Two new idler roller assemblies provide better control of the media
through the print path resulting in better print quality and more accurate
placement of printed items
DA80F-Specific Improvements
• New feeder clutch added
• Added auto-tensioner on drive belts.
• Media thickness range increased from 1/8" to ¼"
