If it flickers alternately, you can reinsert the special ink cartridge.Then tap the printer.If it doesn't work again, it may be a problem with the cartridge holder.You have to pop open the clip, and then use a soft cloth or a soft bristle brush to clean the ink jet head under the ink cartridge holder, which is like a grid of small pieces of metal in rows.Clean and dry before reinstalling.(Be careful not to remove the rubber washer inside the ink cartridge holder.)
Large format, which can be customized to 330 x 1118 mm paper. The company needs it to print certificates, supports network printing, and the effect of printing photos is also good

Consumables are a little expensive, and hard cards may not be printed for U-shaped paper feeding
summary
In a word, this is a powerful printer with good quality and price
However, the printing effect is poor, especially for printing pictures, but printing small photos is a problem. A6 (10X15cm) photo paper does not feed paper, or it will send paper directly for half a day without printing. If you want to print photos, you have to print A4 photo paper. Experiments have repeatedly considered that the power of feeding paper is too small, which should be congenital.
The modified HP7000 uses the original chip (permanent use), and uses a replacement ink cartridge (without chip) to print without color deviation (basically the same as the display). Is 45 color ink expensive?If you can't do it again, you can bottle water yourself. It costs 10 yuan. One bottle can bottle three times. It is not recommended to use continuous confessions. Bottles and lines are too wordy and troublesome. Instead of ink, one set can print four A3 photo papers, and there are still gaps left

It's not fine enough. It's better to change it to six colors

I'm afraid the manufacturer will harmonize this machine. The ink cartridges of this machine are independent and the print head is detachable. Do others have them?
The printing effect is very good. The old ink cartridge with its own print head is incomparable

The paper feeding in HP's corner was poor in the past. A little suppression of D paper will easily cause paper jam, and the print head is easy to break, and the consumables are expensive
summary
It is not recommended that customers with high print quality do not need to buy
I just started to use it. The machine is very large and basically meets the needs. The only thing is that the sound is too loud and the print quality is average
