Principles of Operation

High Volume Finisher (HVF)

Figure 23

. The HVF performs collating, stacking, stapling and optional hole punching opera-

tions on paper delivered (face-up or face-down) from the IME. The HVF offers two trays: a
stacker tray with a capacity of up to 3000 sheets (reduced to 2000 if Tri-Folder is installed), and
a top tray with a capacity of up to 250 sheets.

The HVF has several optional components:

•

Booklet Maker - collects and processes IME output to form booklets from A3, A4, 11 x
17, 8.5 x 14, 8.5 x 13 and 8.5 x 11 short feed stock to form A4, A5, 11 x 8.5, 8.5 x 7, 8.5 x
6.5 and 8.5 x 5.5 booklets respectively (stapled or unstapled) and stack booklets on a sin-
gle tray. Staple and fold modes are user-selectable.

•

Post-Process Inserter (PPI) Tray 6 - allows a minimum of 250 sheets, such as cover
stock, to be inserted into a build job, without having been passed through the IME. The
PPI cannot handle tab stock.

•

Tri-Folder - mounted to the right-hand side of the HVF Booklet Maker, provides either a
straight-through path to accommodate the production of booklets, or an additional fold to
create C or Z folds (the first fold being created by the Booklet Maker).

NOTE: When a Tri-Folder is fitted, the stacking capacity of the main HVF tray is reduced
to 2000 sheets.

•

Hole Punch Modules (LCSS or HVF) - These are options providing 2 or 3 hole options,
4 hole, Swedish 4 and Legal 2 hole. For the LCSS, the user may select any of the five
hole punch options without restriction. For the HVF, the hole punch kits are located in a
mount. Therefore the user must purchase one of the two basic hole punch kits (2 or 3
hole) as a prerequisite to permit fitting the 4, Swedish and Legal hole punch kits.

System Electronics

What follows is an overview of the primary electronic components. The discussions begin with
the power supply.

Power Supply

The auto-ranging power supply provides AC and DC power for all systems electronics, motors
and heaters. The power supply employs three separate switching supplies. The 3.3V ESTAR
and +17V outputs are supplied whenever the power switch is closed (the green LED on the
power supply indicates these outputs are available). The remaining outputs are supplied by
two separate converters when requested by the printer. +24V, 12V, and +5V outputs are sup-
plied by one converter (as indicated by the amber LED), and the 50V outputs are supplied by
the other (as indicated by the red LED). No other outputs are available unless the 3.3V ESTAR
and 17V outputs are on. Refer to WD 1.3 for more details.

AC Input

The Power Supply’s AC input specifications are listed in

Table 1

If the AC power is interrupted for any period of time, the power supply powers up based on the
power switch position. If a current limit is exceeded, or an over voltage occurs, the power sup-
ply can be re-started by cycling the AC line. The power AC line is required to be a minimum of
250ms when cycled.

AC Output

Refer to

WD 1.6

and

WD 1.7

Power Distribution PWB. The power supply has eight, triac-con-

trolled AC output channels. Each channel is controlled by the IOT on a half-line-cycle basis.
The IOT enables the triacs according to the heater demand and input voltage. A half line cycle
dropping algorithm is used (for example, the heater will be on for one half line cycle, followed
by off for seven half line cycles) to control the average power supplied to the heater.
