Also, ensure that the MFP only prints the required copies to ensure data security. Will your company need to manage sensitive information?Īccess to the features of a photocopier should be controlled with PIN numbers or passwords. Look at the fax capability of the MFP, which today is likely to use the cloud as well as direct dial to another fax machine.Ĥ. Many vendors now offer the option of sending samples by post.įax is far from a dead communications medium, with many large businesses still needing it. If possible, look at samples of print and scanned output before making your choice. Many of the latest photocopiers using advanced print technologies that were, up until a short time ago, only found in high-end printers. How important is quality of scanning and printing? Look closely at the stated capacity and match this to your business' workload.Ģ. Photocopiers in the shape of multi-function printer come in all shapes and sizes. Can the photocopier your business is considering handle the capacity needed?
What to consider when buying a photocopier?īelow are five points to consider when putting together your checklistġ. In the past, MFPS had a bit of a bad reputation as a 'jack of all trades', but they have made significant improvements both in terms of quality, value for money and onboard features. The main drawback of the electrostatic process was the special paper that was needed, a kind of paper that felt different from ordinary paper and was more expensive to produce and to mail.If you're looking for the best digital copiers, then you've come to the right place, as on this page we've ranked the best photocopiers money can buy. The electrostatic copy process became less popular when xerographic processes were improved. When the paper is passed through a pair of rollers, the toner is pressed into the copy paper, forming a permanent positive image that corresponds to the image on the original document.
Next, the exposed copy paper is passed through a toner bath, where positively-charged toner attaches itself to negatively-charged areas on the copy paper. In this respect, the copying process is exactly like that which occurs in xerography. Light striking the copy paper removes negative charges placed by the charged bar, leaving charged sections that correspond to the absence of light, that is, the dark places on the original document.

Light reflected off the original document is then reflected by a series of mirrors to the treated copy paper which has been passed into this section of the machine. Dark portions of the document, such as the letter "a" in the document, do not reflect light.
In the next section of the copy machine, the original document is exposed to light, which reflects off the white portions of the document (as in a xerographic machine). Within the charging bar, the zinc oxide coating picks up a negative electrical charge. When that paper is fed into the copy machine, it is first passed through a corona charging bar, similar to the one used in xerography. The paper used in electrostatic copying is treated with a material consisting of zinc oxide combined with a thermoplastic resin. The major difference between these two processes is that in electrostatic copying, the endless photoconducting surface is omitted from the machine and the copy paper is specially treated to pick up the toner. A process somewhat similar to that used in xerography is electrostatic copying.
