Summary: I have owned this printer/copier for over five years and never was disappointed once with it. A little noisy but has worked flawlessly. I installed it on a desktop and then printed from other computers by network through that main computer. My biggest disappointment is that I have gradually replaced the computers in my home with newer ones and, very unfortunately, Windows 7 does not support this printer/copier.
Summary: Sharp Electronics AL-1642CS Digital Laser Copier/Printer with 2nd Paper Tray . This product arrived with a broken toner cartridge, although sharp replaced it free of charge. That is the only nice thing that I could say about Sharp. A big problem I had with this machine was its frequent paper jamming issue that resulted in wasting at least 20% of the paer fed to the machine.
Summary: easy fail to work, it did out of order twice within the first 6 months! for the 1st time, the customer service told me I have to pack the machine for return to repair, but they won't provide any boxes and packing material. you know, packing this kind of big heavy thing well is kinda head-ache! for the 2nd time, I was told to input a set of commands to resume the machine to service. well, no problem.
Summary: Excelente produto. Já conhecia a AL1645 e esta AL1642 tem como diferencial o alimentador automático e duas gavetas. No mais são iguais. Ambas só fazem frente e verso em papel carta de modo que fica desabilitado pois só uso A4 ou ofício.
Pros: Alimentador automático, duas gavetas, boa qualidade de cópia, econômica, facilidade de assistência técnica e peças.
