Canon MX860 – images appear washed out
So, I’m now trying to use my Canon in anger, to scan some documents, and have found something that is actually making me angry.
If you scan a colour document, it will perform some kind of optimisation that will wash out normal colours; it seems to apply contrast and brightening in one. I expect this is for archiving/smaller file size/better OCR performance. This didn’t seem so bad, but then it came to scanning some receipts and an MOT document. Anything with faint machine-type, became almost unreadable once scanned.
Some playing around, revealed that it IS capable of scanning with ‘normal’ contrast, but this is actually quite difficult. If I force it into photo mode, then it doesn’t apply the colour correction, and faint type is still visible.
However – that’s easier said than done. For example:
– If scanning to the MP Navigator software, it’ll automatically use the Document mode: even if I tell it to scan colour photo, and turn all correction off
– If scanning direct to memory card, then there are 4 options: Document (Platen), Photo (Platen), Document (ADF Simplex), Document (ADF Duplex). Of these, only Photo (Platen) gives the required results. Of course, that means there’s no ADF option for scanning without washed-out effects
– If scanning using other software (eg. MS Office Scanning), then there are two driver options. The native one (Canon MX860 ser_xxxxx) gives the same washed-out appearance as before. The WIA Driver (Canon MX860 WIA, Windows-compatible) DOES keep the detail in the picture. However – THAT driver doesn’t support the ADF, or any other scanner features. Even playing around with MS Office Scanning, the best I can get is to scan one side, then feed the paper back in the other way around, and scan the other. So why pay for the duplex ADF?
I’ve phoned Canon Support – and a UK-based agent answered within 2 minutes, which was really impressive. However – they tell me there’s absolutely no way of changing the default settings on the scanner itself, so I’m restricted to this basic, manual method of scanning.
