Photocopiers FAQs

Digital versus Analogue?

Digital copiers read the original using a CCD unit, which converts the optical data into an electronic form. It’s then processed to ensure optimum copy quality before a laser writes this information onto the photoconductor. This is a similar process to the way Laser printers work. Analogue copiers use a series of mirrors and lens to direct the light reflected from the original to the photoconductor’s surface to create the image.

What is Scan once print many?

In Digital Copiers the original is scanned once and the digital image is placed into memory. It is then printed out as many times as required. This is faster than Analogue copiers, as these need to scan the original once for every copy made. Therefore 20 copies would require 20 scans. This can cause different levels of copy quality across multiple copies. Digitals do not suffer from this as each original is scanned only once and the image stored in memory is used again and again to produce the required number of copies.

What is Duplex?

Double sided output, so both sides of the sheet are printed on.

What is Sorting?

Sorts copies into sets. 10 originals copied 10 times using sort would give 10 identical sets.

What is Grouping?

Basically the opposite to Sort. Copies are grouped together. 10 originals copied 10 times using group would give all page number 1’s together, all page number 2’s together etc.

What is Bypass tray?

Side tray on most machines. Allows the loading of heavier paper or card stock than the cassettes. Designed also as a quick access tray to save opening the main cassettes to load just a few different sheets of paper or card stock.

What is Job build?

Gets around the limitation of the ADF’s original capacity by allowing more originals to be added once the initial batch has been scanned.

What is an ADF?

Automatic Document Feeder. Sheet feeder on top of the machine that allows several, usually up to 50 or 100 sheets, to be loaded and automatically fed in scanned and returned by the feeder.

What is LCC/LCT?

Large Capacity Cassette or Tray. Holds a larger amount of paper stock than a normal tray. 1000 to 3000 sheet LCC/LCT are commonplace depending upon model of machine.

What is Black/White reverse?

Basically everything white on the original is printed as black and visa versa.

What is Margin Shift?

Shifts the image over by an adjustable amount. With modern digital machines the margin shift can be from any side of the page whereas with the older analogue type machines it tends to be just from the lead edge towards the trail edge of the document.

What is Dual page copy?

When copying an A3 sized book or magazine from the platen glass the original is scanned half way and one copy is produced then the second half of the original is scanned and that copy is produced. It’s designed to counteract the spine mark that appears while copying books or magazines that can’t lie flat on the glass. Can also be combined with Edge Erase & Centre Erase.

What is Edge & Centre Erase?

Deletes an adjustable border of usually 10mm around the whole page, and also in the centre if required, to give a clean appearance to the output. Useful for removing fax headers while copying faxes.

What is Independent X Y zoom?

Independent X Y zoom allows the X-axis and the Y-axis to be enlarged or reduce independently of each other.
