The reasons I had discounted paper feed as the problem are as follows:- The feed rollers are regularly cleaned, at least every week and there has been no problem with pick-up. If this was a feed problem then some variation in printing could be expected when using the standard weight paper. The...

Many thanks for your input. My reason for asking is because I am noticing a difference of where on the paper the printer starts to print. If reasonably heavy bond paper of 32lb is fed from the rear tray the printer will always print accurately on it. On the other hand, if a lightweight paper is...

Can anyone tell me the means by which Canon printers (the iP4950 specifically, or Pixma in general) detect the leading edge of paper as it is fed from the rear tray so that it knows when to start printing and if the sensor can either be reset or replaced.

Thanks - Which commands would you suggest I try? The effect I described doesn't appear to be as a consequence of the actual feeding of heavy paper. As mentioned, up to 400gsm feeds satisfactorily in all three models

I have printed a lot of wedding invitation cards on 300gsm and above with Canon printers. Using good quality like ColorCopy will avoid thickness issues. Any Canon with a rear feed should do the job

The three printers I referred to are Canon iP4500, iP4950 and MP610. I only use the rear paper trays. The feed rollers are regularly cleaned with PlatenClene and there isn't a problem with the initial feed of either paper or card. Up to 400gsm feeds successfully in all of them. The roller feed...

I have three different models of Canon printers and have found that depending on the thickness of paper being used the position of the image is altered. Up to about 200gsm the printers print accurately. Above that they start to print too soon. The heavier the paper the greater the discrepancy...

I agree with Lukasz that if the pigment black is substituted with dye then there can be a slight color cast. This seems to be because dye black isn't actually black but usually very dark brown bordering on red but depending on the manufacturer I have also seen it bordering on blue. Using dye...

Yes, Stratman, the printer uses pigment black irrespective of the type of image where plain paper is specified. This is because the MG610 printer doesn't have the option of later models to specify photo printing. Selecting photo paper does, indeed, force the printer to use dye black but the...

I mentioned a "slight" ridge. It doesn't originate in-house but is supplied like that (in A4 size) by mainstream paper manufacturers like Mondi. Although the ridge might be barely detectable, it can be enough to make a difference as to whether to not anything other than a fairly new printer can...

In an earlier post I questioned why I was experiencing problems feeding card stock from the rear tray of MG5250 and MP610 printers when card was loaded into the tray but not when the card was fed singly. Also, there was no problem when paper was loaded in the tray. A close examination suggests...

I have been using an MP610 for printing photos on plain paper. This works well except that where the image requires a fair amount of black the print dries too slowly causing one print to smudge the next on the output tray. I assume that because plain paper is specified the printer is using...

Many thanks for the suggestions. I have thoroughly cleaned the rollers of my MP610 with alcohol but have not seen any improvement. What I do not understand is that there is never any problem with feeding heavy cardstock if it's one card at a time. I have an iP4950 which continues to work...

I have been a big fan of Canon printers for several years not least because all of the Pixma models I have used have been capable of taking heavy card stock from the rear tray. However, I have found that this capability reduces as time goes by. Heavy card can still be fed without any problem if...

A TALE OF TWO PRINTERS! Printer – Canon iP4850 Installed cartridges – Not recognised assumed of Chinese origin Approx length of time unused – 2 years Nozzle check – extensive blocks Clean according to CLS advice to rinse with water Nozzle check – better but still extensively blocked Immersed...

mikem65d's post needs to be considered in its entirety. Not only did he stop using his printer for periods of 6-8 months but the last standstill was for about the same time as mine (i.e. 2 years) The fact he was able to operate it again after this time with so little problem is significant. I...

mikem65d's experience would seem to be different!

Following my last post I decided I would follow the original advice and immerse in isopropanol. After 12 hours inks was still coming from the printhead so I left it in for another 12. Put the printhead back in the printer and the nozzle check was greatly improved but still not perfect. Soaked...

Did a nozzle check after installing a new set of inks. Lots of blocked nozzles. Cleaned the printhead as recommended by cls - much better but still blocks.

I have been given a Canon iP4850 which has not been used for at least two years. It has been suggested that before trying to use it I remove the cartridges and printhead, immerse the printhead in isopropanol overnight then replace the printhead and insert a new set of cartridges. Is this good...
