The Canon PC420 is a monochrome laser copier designed for the home or small office user. Its portability and compact size make it an excellent choice for users who need to make copies on the go. Its price may be a bit high for its feature set.
The Canon PC420 laser copier is about the size of a standalone scanner with an input and output tray that fold out to either side of the unit. This makes it extremely portable, and allows users to take their copy machine to the documents, instead of taking the documents to the copy machine. This could be extremely useful for students doing research at a library, for example, allowing them to take the machine into the library for copying on the fly. It even includes a handle for easily toting it around.
Setting up the copier is quite simple. Users simply unfold the input and output trays, plug the unit in, and it is ready to copy. The copier has a very fast warmup time, so it is ready to work almost instantly. It has many adjustments available for exposure to ensure a quality original scan, improving the copy quality.
Canon PC420 toner cartridges have a capacity of 4,000 pages, though the original laser toner cartridge has a capacity of only 1,000 pages. The copier printer toner cartridge includes both the toner and the drum, so users don't need to replace each separately.
Copy speed is fast, at around 4 copies per minute. Given that the unit has only a flatbed scanner, with no automatic document feeder, copy speed may depend quite a bit on the user's ability to feed pages quickly. Copy quality is generally very good, especially when using the scanning settings to get the best possible scan of the original. Colorful options are available elsewhere, like in the LaserJet 2500 toner printer.
Overall, the Canon PC420 laser copier is a great choice for the user who needs portability. Its price tag is higher than similar models that lack portability, but offer faster speeds.
