HP Designjet 820MFP series


HP Designjet 850MFP (Q6685A)


The HP DesignJet 820 MFP is a wide format multifunction printer, scanner and copier sold as a single product - a printer and scanner with a console. It provides workflow integration for cartographic and engineering environments handling oversized documents up to 43 inches wide and any length.

The DesignJet 820 is based on the 42 inch 800ps printer and DJ4500 43 inch high resolution scanner with touch screen and keyboard. An intuitive graphical interface steers users through copying, scanning to CD or DVD  or to network files.

The DesignJet 815 MFP Q1279A was similar but has lower capability; lower resolution and half the scan speed.

The current MFP model is the T1100MFP -Q6713A -. The new model is similar but based on a significantly faster 6-ink printer.


Control:

LCD touch Panel with easy to navigate menus. Scan preview, Scan to file, Scan to CD-ROM, Scan to print, Collate copy, Copy.


Similar specification to the DesignJet 800. A1 black diagrams in 60 seconds, colour in 90 seconds.


Scanner Abilities:

Appears to be similar to the DesignJet 4500 scanner but some of the spec sheets suggest lower speed and lower interpolated dpi


2400x1200 dpi. Minimum line width is 0.0423mm (0.002 inch) and Line accuracy is +/- 0.2% or 0.38mm whichever is greater.


Paper Handling:

Sheet feed, roll feed, automatic cutter.


Memory:

160 MB RAM in the printer. 1GB RAM and 23GB disk for scan jobs.


Interface:

IEEE 1284 compliant Centronics parallel (ECP).


Network:

EIO Slot with JetDirect 615n installed

Spares:

The main spare needed is the carriage belt - it takes a lot of wear as the heads move back and forth. The carriage trailing cable also wears out due to frictional contact with  the base of the machine - the tracks become exposed and crack.  The encoder strip  gets its marks scuffed. Eventually the ink tubes will spring a leak.

Although the life of these parts can be quite different it is often convenient to replace them all at once, to do this buy a maintenance kit.
