HP4-R2 TRAINING
DUPLICATOR ENGINE
COURSE OVERVIEW
The course is broken up into several modules. This section outlines these modules.
The course covers the HP4-V2 and the optional peripherals. Software is covered in
separate courses.
The mechanisms are very similar to the Pink Gold/HP4 and Silver duplicator series.

Product Concept
Mid-range model with more capabilities than current
models in this range
zReplacement for the HP4 and Pink Gold models
zThe engine is based on the Pink Gold series.

Options
50-sheet Document Feeder
Colour Drum
A4 Drum (black only)
Tape Dispenser
Platen Cover
There is no sorter, Opal, or LCS.
The drums cannot be used with the Opal or HQ-Opal.
Introduce the range of available options.
¾The document feeder is the same as used with the Sapphire 2 and HP4.
¾The tape dispenser is almost the same as used with previous models. It is
modified for RoHS compliance.
¾The platen cover is the same type as used with previous models.

Platen Cover/ADF
The customer needs one of the above options.
This is because a platen cover is not installed at the
factory.

Sales Points
Good image quality
zHigh-quality ink and masters
Quiet
zSound-proofing materials are added to areas where
noise occurs
zNoise-generating mechanisms are modified
Reliable
zImproved paper delivery table
zPaper feed retry
Ink and masters: Same as the HP4
Slightly quieter than HP4, because of these modifications
Paper delivery table: The new mechanisms from the Emerald are used.

Good Image Quality
High-quality Ink and Masters
New Type Old Type
Same as the HP4.
In older models, fibres in the master were sometimes tangled. This blocked the flow
of ink through the master to the paper.
The new master is improved. Also there is an additional porous layer, the film is
thicker, and the holes in the master are sharper.
In addition, the ink percolates through the master more evenly.

Good Image Quality
High-quality Ink and Masters
As a result
zBetter solid fill-in
zSmoother halftone and photo images
• In addition to the improved master and ink, image processing is
similar to that used in black-and-white copiers. This means that all
types of originals (text, photo, text/photo) can be reproduced
accurately.
zNo set-off, no print-through, drastic reduction or roller marks and
stains
• Good-quality duplex and colour printing become possible
zLower ink consumption by 20% from the Pink Gold
• This is in spite of the better solid fill-in. Ink supply to the paper is
more accurately controlled because of the smaller holes and the
properties of the new ink. As a result, there is less waste.
zDurability of masters is increased from 2,000 prints per master to
4,000 prints per master
Same as the HP4.

Auto Print Pressure Control
Without auto print pressure
control:
zThe print is paler if the print
speed is faster
zThe print is darker if the
temperature is higher
There is a thermistor near
the drum to detect
temperature.
The machine automatically
changes the print pressure,
based on the print speed
and the temperature, to keep
a constant image density.
Same as the HP4.

Reliability
Paper Delivery Table
Improved paper delivery
table: Plates are attached
on each side
The tabs on the inner
sides of the plates catch
the edges of the paper.
Because of this, the
paper falls more slowly
onto the delivery table.
This reduces ink stains
on the rear sides and
stacks the pages more
evenly.
The user can move these
plates to one of two
positions, depending on
the paper type.
This mechanism also improves paper alignment.

Paper Feed Retry
Paper feed retry
zIf the registration sensor does not detect the paper
feeding into the machine, the feed mechanism tries
again.
Same as the HP4.

Energy-saving
This model has energy saver and auto-shut off
modes, like photocopiers.
Compliance with directives on hazardous materials
(RoHS) and waste (WEEE).
Auto off mode is new for this series.

Exchangeable Keys
A technician can exchange the ‘Master Making’ and ‘Print’ keys.
zSome customers may prefer the keys to be exchanged.
The functions of the two keys automatically change when you
do this.
The procedure is in section 3.2.3 of the service manual.
