Original Handling Capabilities

While scanning speeds and duty volumes

may be based upon perfect standard letter

sized office grade, laser printer paper, there

is a much wider range of media substrates commonly

used and handled in the world every day.

Coated Surfaces Help Printing But Hinder Scanning:

Friction rollers, which grip and guide originals through the

document feeder, work very well on standard fibrous office

paper. Now consider the account department administra-

tor who scans hundreds of multi-part purchase orders

printed on carbonless paper or a customer service depart-

ment processing customer correspondents using coated

inkjet paper. Both media supplies include a chemical sur-

face layer that aids printing, but reduces friction that make

rollers slip and mis-feed.

Damaged Originals Can Create Rejections:

Perfectly crisp flat edges are an ideal medium to feed

through a document feeder. Now consider the paralegal

processing discovery documents complete with ripped out

corners left after staple removal or torn punch holes.

Some scanner mechanisms are designed to shutdown at

the merest detection of imperfection to avoid jamming

risks while others battle through with more forgiving fed

mechanisms that adjust to less than perfect conditions.

Size Matters:

Most scanner units include multiple friction rollers, which

share the workload and maintain a straight feed path.

Smaller originals like invoices, business cards, index

cards, etc. may only get captured and fed through the

scanner by one set of friction rollers, which can result in

more crooked mis-feeds and jams.

There is a Perfect Weight

The flexibility, resistance, and other physical factors of

standard office grade paper make it the ideal medium for

high speed scanning. As paper weights get further away

from the ideal, such as thin delicate newspaper or heavy

purchase warranty registration card, so do the incidences

of mis-feeds.

BERTL Tests Span Real World Situations:

To see how scanner feed mechanisms handle the wide

range of possible media types, BERTL analysts stack the

feeder with a wide range of media types and report on

how each original type is handled.

Original Feeding Test Observations:.

The reversing duplex document feeder proved to be more

reliant to extremes of original scanning than some other

units tested recently (with only business cards falling be-

low the capabilities of the device), despite its two-pass

technology design. Unlike some other Ricoh document

feeders, there is no gap between the input paper path and

the white background plate that is used as the reference

for the platen scanner. The Ricoh Aficio MP1350 docu-

ment feeder handled all media types, large and small, thin

and thick with no issues. This places the Ricoh in a strong

position to be taken seriously as a production scanning

resource especially due to its added color scanning capa-

bility and dropout feature.
