Canon Photo Printers: S900 and S9000
Краткое содержание статьи: Canon 2002 is turning out to be even more aggressive than usual! The old S800 series has been replaced by six new printers. Two of these really stand out: the S900 and the S9000. The new series of printers still uses six cartridges, but the number of nozzles has doubled and there is a new border-free printing function. In order to be as thorough as possible, we not only compared them to the S800, but also to their rivals from Epson and HP. The following tests look at speed, quality and photo costs, in detail.

Heads: Advantages and Drawbacks

Heads: Advantages and Drawbacks

The print head block is, as we already explained in our desktop printer comparisons, the core element in the printing process. Print quality depends on it, both when the product is new, and in the long term.

Heads: Advantages and Drawbacks

HP and Lexmark have heads integrated into the cartridges, which means new heads every time the cartridge is changed, at least if you buy original cartridges. The only trouble is that this makes a big difference in the price of a new cartridge and, indirectly, in the cost per page for the device.

Heads: Advantages and Drawbacks

Epson, on the other hand, has a head fitted to the printer. This makes the cartridges quite a bit cheaper, but, as the heads stay in place, they wear out in time. So there are three risks:

  1. When it is not used, the head is inclined to clog because the ink dries. There is not much chance of this with HP and Lexmark, where the heads are always new. This becomes fairly tiresome in time, because the heads must be cleaned so often, and cleaning is a long process -- noisy and ink-consuming.
  2. The more you print, the more wear on the heads. Results towards the end of the device's lifetime are likely to be of poorer quality than at the beginning.
  3. The printer warranty also covers the head. When the warranty runs out, you will have to change your printer if the heads cannot be unclogged, unless you decide to have it repaired - but this is expensive and not always the wisest decision.

Canon has semi-fixed heads. Actually, they are integrated into a separate block and are neither part of the printer nor the cartridge. So, you should change the block when you think the print quality is no longer up to snuff, or when the heads are completely clogged.
