PRODUCT APPEARANCE
The first few slides illustrate what the machine looks like, with some of the options
connected.
Here we see a finisher and an LCT attached.
The ARDF (capacity: 100 sheets) is standard equipment for this model, not an
option. It has a CIS built in, which allows both sides of a double-sided original to be
scanned at the same time.
The three built-in paper trays are as follows:
¾Tray 1: 1550 sheet x 2, tandem LCT
¾Trays 2 and 3: 550 sheets each
¾In addition, the built-in bypass tray has a capacity of 100 sheets.
¾Optional LCT: 4,000 sheets (2,500 if the LG/B4 kit is installed)
¾Adding it all up, the machine has a maximum paper capacity of 8,300 sheets
(A4/LT).
The tandem tray (main frame, tray 1) can only handle sizes up to A4/LT. The
DLT/A3 tray allows tray 1 to hold sizes up to DLT/A3 (1000 sheets). However, this
will not be a tandem tray.
Trays 2 and 3 are adjustable to hold a wide range of paper sizes.
The LCT can only handle sizes up to A4/LT. The LCT can be fitted with an LG/B4
option to allow it to hold paper sizes up to LG and B4.
¾However, if the tray is modified in this way, some short paper sizes, such as
A4SEF, cannot be added, because the end fence will not reach them. A4LEF
can still be used.
The cover interposer is used with the finishers. It inserts cover sheets in the
locations specified by the user.

Interposer Tray
This slide shows how cover sheets are fed into the paper feed path between the
mainframe and the finisher.
The cover interposer allows cover sheets to be inserted at the times selected by
the users. It is installed between the mainframe and the finisher, but is like an ADF,
feeding cover sheets into the paper feed path between the copier and the finisher.
¾It requires a finisher, but cannot be installed if the optional mailbox is
installed.

Product Appearance
Optional Mailbox (nine bins)
Optional Booklet
Finisher
Optional Z-folding unit
PRODUCT APPEARANCE
Here, the cover interposer is replaced with a nine-bin mailbox.
A z-folding unit is also installed. This can only be used with a finisher (B700 or
B701, not the B706).
¾It must be installed between the finisher and the copier.
The mailbox bin capacity is 100 sheets per bin. The mailbox can only be installed if
a B700/B701 finisher is installed. But it cannot be used with the B706 finisher.
¾In the B700/B701 finishers, a junction gate directs paper either to the proof
tray or to the other output trays. If the mailbox is installed, another junction
gate inside the base of the mailbox then directs paper either up to the mailbox
or out to the proof tray.
¾The B706 finisher cannot divert paper up to the mailbox.

Paper Path to the Mailbox
Proof Tray Junction Gate
(Inside the Finisher)
Entrance Junction Gate
(Inside the Mailbox)
In this model, the mailbox is connected to the optional finisher, not to the main
copier. This is unusual.
The proof tray junction gate diverts the paper either out to the proof tray or into the
finisher for various stapling, shift sorting, or folding operations.
If the mailbox is installed, the entrance junction gate inside the base of the mailbox
then diverts the paper either up into the mailbox or out to the finisher proof tray.

Engine Options - Finishers
B700: 2000-sheet Booklet Finisher (same as Venus-C1)
zThis finisher has three trays: a proof tray on top of the finisher,
an upper (shift) tray, and a lower tray for booklets.
B701: 3000-sheet Finisher (same as Venus-C1)
zThis finisher has two trays: a proof tray on top of the finisher
and the upper (shift) tray.
zThis finisher does corner stapling only. It does not have a lower
tray for stapled and folded booklets.
B706: 3,000-sheet finisher with 100-sheet stapler (same as the
B140 series)
zThis finisher contains a jogger mechanism for z-folded output.
But the z-folding unit cannot be attached to this finisher when
installed on the B140/B246 series.
There are three types of finisher for this model.
A range of hole punch units is available for each finisher.
The B706 finisher with 100-sheet stapler also has an optional jogger unit which
tidies up the copy stack as it leaves the finisher exit. The jogger unit can only be
used with the B706.

Z-folding unit: This unit puts two folds in the output before feeding it out.
¾B140 series: Uses the B660-17, -26, -27 z-folder
¾B246 series: Uses the B660-57, -66, -67 z-folder, not the same as the B140
series.
Punching and z-folding cannot both be done in the same job.

Sales Points
Improved Usability
zLarge WVGA display (8.5 inch W-VGA panel, 800x480)
zReduced steps for LDAP search
z“Simplified display” button: Displays fewer functions.
zLogin/Logout Hardware Key
zBetter access for user authentication
Productivity
zTwo-sided scanning ADF: Faster two-sided copying
Security
zCopy Data Security Unit
zData Overwrite Security unit
zAuthentication
Quick Start: 30 seconds to warm up
Two-sided scanning in the ADF
The ARDF contains a CIS that scans the reverse side of originals passing through
the ARDF. The CCD in the scanner scans the front side. This means that both
sides of two-sided originals can be scanned at the same time. There is no inverter
mechanism in the ADF.
Because of this, the copying speed is unchanged for ADF 1 to 1 copying.

16
16
Faster Warm-up
To decrease warm-up time, a smaller number of steps is done
immediately after the machine power is turned on. These are
the steps.
zDrum potential sensor calibration
zDevelopment bias adjustment
zGrid voltage adjustment
zLaser diode power adjustment
The number of steps is controlled by SP 3904.
The default is 0 (the minimum number of steps is done), and
the charge corona wire is not cleaned. The machine is ready
after 30 seconds.
Other settings of SP 3904
z1: The charge corona wire is also cleaned. Warm-up time is 70
seconds
z2: Full process control is done. The same as the B064. Warm-
up time is 240 seconds

Reliability and Service Targets
Average Monthly Copy Volume
zB163: 25 k
zB140: 30 k
zB141: 50 k
Maximum Monthly Copy Volume: 150 k
PM Interval: 300 k
EM Interval: 100 k
MCBC: 75 k
Estimated Unit Life: 9000k prints or 5 years
Time necessary to install the machine: 30 minutes for the main
copier.

18

Target Yields
Toner: 43k copies per bottle
Developer: 350k copies per bottle
zThe PM cycle is 300 k, so the developer will often be
changed at 300 k.
Compatibility
zThe toner and developer can be used with the B064
and B140 series.
zThe OPC drum is new and cannot be used with the
B064 and B140 series.
TARGET YIELD
Toner yield is based on a Ricoh 6% A4 chart under normal operating conditions.
