[1] GENERAL DESCRIPTION
1. Features
[Small]
• Compact design
• Small area for operation
[Speedy]
• Warm-up time 30 sec or less, the first copy 5.9 sec ∼ the fastest in
the class.
• The automatic document feeder (standard provision in the SF-
2214 only) increases copy productivity.
• The photoconductor and the peripheral parts are integrated into
units. The novel two-component development system eliminates
the need for developer replacement. Parts replacement proce-
dures in the fuser section and the paper feed section are simplified
to remarkably reduce maintenance time.
[Soft]
• The energy save mode reduces the total power consumption.
• The noise limiting design results in the quietest machine in the
industry (46 dB).
• Ozone generation is limited.
• Use of materials which can be recycled.
User simulation
The user can select the desired operating conditions easily. Auto
clear time, power save mode time, power save mode warm up time
can be set by the user simulation.
2. Target users
Average copy volume of 2,000 ∼ 3,000 sheets/month (max. 10,000
sheets/month)
3. Novel technology
Novel two-component development system
During copy process, developer is substituted little by little to prevent
image deterioration. Replacement of developer is not needed. A de-
veloper/toner recycling method is used.
SPF (Single Pass Feeder)
When documents are placed in the feed port and the PRINT key is
pressed, the SPF will feed the documents automatiaclly. The SPF
enables one set of copies for one set of documents.
4. Novel functions
Power save function
After a set time, has passed since a copy run has finished, the pwer
save function operates to save energy. There are two kinds of power
save function as shown below. The preferred power save mode can
be selected by the key operator.
1) Pre-heat
• The temperature in the fuser section is lower than that in the ready
state.
• Within 10 sec after completion of pre-heating, the machine returns
to the ready state.
2) Auto power shut off
• Power supply to the fuser section is shut off.
• The time required to return to the ready state and turn on the
ready lamp after completion of auto power shut off is the same as
warm-up time after turning on the power.
