Product Dynamics

Imaging Unit Design

The Ricoh Aficio 3228C uses laser

technology.

There is still great controversy between

whether laser or LED technology is the

better way to go. LED uses fixed LED

arrays to create the image on the moving

drum while laser technology, as the name

suggests, uses one or more laser beams

that are directed to create the image on

the moving drum via rotating mirrors.

LED proponents claim that laser imaging

technology is more prone to environmental

fluctuation while laser technology

enthusiasts promote that laser imaging is

more flexible allowing smaller and different

sized dots to be created.

In reality, BERTL has seen good and bad

output from both laser and LED printers

over the years and advises users to look

beyond the theory of the imaging process

and see how the device is able to handle

the specific workload critical to your

business. Indeed, many manufacturers

include both LED and laser imaging

technologies in their range.

Just remember not to get sucked in by the

hype and focus on what you need the

technology to do, — create good quality

output for your needs. A device that

produces good PowerPoint presentation

slides may create poor halftone

photography, making it ideal for some and

a waste of money for others.

The imaging drums are aligned in a

tandem fashion, one drum for each color.

The drums, as you can see from the top

photo are positioned at a 45 degree angle

with the paper passing along the transfer

belt over each drum in turn, where the

image is built up. This layout allows the

Ricoh Aficio 3228C to maintain a more

Replacing toner is a simple process

compact footprint compared to some rivals

that have the imaging units in a line

parallel to the floor.

End User Maintenance

While virtually all devices will be sold with

a maintenance contract, the trend is

towards designing devices that allow end

users to carry out routine maintenance

tasks themselves in an emergency.

Toner supply changes are easy, with the

side door opening to reveal the four toner

bottles.

To gain access to the imaging drum

themselves is not as easy, requiring the

removal of several screw — a factor that

might put some end users off.
