Major Differences from the B283-65 and B282-65
ID Copy Function
Allows copying of both sides of an ID card
(or other small document) onto one sheet.
No alignment problems. Don't have to feed
the paper back into the machine.
Increased Copy Speed
Multicopy rate has been increased for the
B282-69. (18 cpm ⇒ 20 cpm)
ADF 1 to 1 speed is still 18 cpm.B283-69 multicopy rate is unchanged. (18
cpm)
Design Change
Internal tray is blue.
NIB
Front
Back
Front
Back
The ID Copy function is a requirement of the Chinese market. The Chinese ID
was changed in 2007 and now has important information on the reverse side. Financial institutions and government offices especially need to easily copy both sides.
ID Copy is different from Combine Copy function in that the output size is the
same as the original.
Users can identify output documents more easily with the blue internal tray.The network interface board (NIB) is a new internal option.

Inverter Tray - 1
(Duplex Model B282-69 only)
Back corner edge
of Inverter Tray
Check that the back corner edge of the Inverter tray is fully against the back of the slot (see following slides for details).
Note: This is only applicable to when making duplex copies/prints. For single-
sided output, the paper doesn’t come out of the slot just above the Inverter Tray. For this reason, if the Inverter Tray is out-of-position, single sided printing/copying will proceed smoothly, with no jamming or errors, while duplex printing/copying can produce a jam.

Inverter Tray - 2
(Duplex Model B282-69 only)
Back corner edge of Inverter Tray
Correct Position
Lock
Incorrect Position
Insure that the back corner edge of the Inverter Tray is fully against the back of the slot. If the back corner edge is away from the back (see right photo above), then duplex printing will jam (see next slide), due to paper hitting the corner edge (see previous slide).
Note: The Lock is easily released by pulling on the tray to remove it from its slots.
Note: This is only applicable to when making duplex copies/prints. For single-
sided output, the paper doesn’t come out of the slot just above the Inverter Tray. For this reason, if the Inverter Tray is out-of-position, single sided printing/copying will proceed smoothly, with no jamming or errors, while duplex printing/copying can produce a jam.
