Maintain the Domino A320i/A420i Pressure Pump by Ourselves

Is it difficult to maintain a pump by ourselves?

It depends, if you are not a tech and just want to try fix the pressure pump, we could purchase a whole set of pump head with motor. It doesn’t require much work, as long as we pin point that it’s the pump which leads to the failure, we can fix the problem by replacing a new set of pump with motor. However, it cost most.

As you may know, the motor seldom goes wrong. The pump head, on the contrary, usually worn out easily. We can tell if the motor working or not by hearing, if the motor vibrates a little and generates a small noise, it’s working fine. Then we just need to replace the pump head.

If we really want to challenge ourselves, we can try fix the pump head by replacing the gear kits. The gear kits worn out and causing the pump fails to work, but it takes some experience to change a new set of gear kit.

9450 Touch Screen Connector

My customer Jack bought a 9450 touch screen last week, when he received it, he found that both the LCD and touch screen are ok, the size fits perfectly. He is satisfied for basically everything, apart from the connector. It doesn’t match his printer.

Jack shows me his connector, which is with 4 cables, while the one I sent him is with 3 cables, so despite the touch screen is fine, he is not able to connect it to his printer.

Connector with 3 and 4 Cables

After getting the feedback from Jack, we work on it asap. It turns out that there are two types of connectors for Markem Imaje 9450 printer, usually it’s with a 3-cable connector, but for some batches, it’s with 4-cable connector. So our tech spend some time to work on the connector, now we have 4-cable connector touch screen too.

How to Fix Videojet Inkcore Overspeed

When you receive our refurbished inkcore, it may have one or two problems. Don’t worry, most of the problems are minor and caused during the bumping transportation, only small checkings will fix them.

I get a feedback from my customer Tom recently, he told me that the newly arrived 1520 inkcore isn’t working, there is no reading from the pressure pump, then he replaced another pump, the problem remains. It seems tricky, but actually, all we need to do is to check two spare parts.

  1. Check the inkcore board. To see if it’s properly wired.

2. Check the pressure transducer

If all the tubes on inkcore board are correctly connected, then we have to look at the pressure transducer. As you can see in Tom’s case, the pressure transducer is cover in ink, the problem is most likely lying here. Tom freed the pressure transducer out by gently move it from right to left little by little, then cleaned it with solvent. We can see there is a small damage on the transducer, which fails to send the pressure pump data to main board. After we replace the pressure transducer, the refurbished 1520 inkcore works again.

Refurbished Videojet inkcore may suffer from all sort of small problems during transportation, such as sealing parts come off and leads to ink leakage, the connection on inkcore board gets loosen, all these we can fix it easliy. When we comes to the more complicated problem, we could try to fix it by replacing another part or return the inkcore to us, we will send you another one or refund it.

Please feel free to contact us if you have any further questions.

I Want This Mother Board…

I know you guys are busy with the continuous inkjet printer maintenance work, sometimes need to drive for a long time, which is time & energy consuming. It’s actually fine, that you send us pictures of the parts that need to be replaced while you are doing the maintenance work. We could quote to you asap, as most of the spare parts for continuous inkjet printers are easy to recognize. For example, if I saw your hand holding a filter, and there was a Videojet printer in the background, then I will know you are looking for new compatible filters, maybe a filter kit. However, this way doesn’t work on boards.

There was a customer, who poured a stream of board pictures to me & required quotation. I can quote some of them, however, some inkjet printer boards, despite their configuration look the same, the prgram in it is different. It’s quite irresponsible to drop a price without stating the detail of the board. So for boards, please do tell us for which printer model it’s applied on first, if we need more info than that, we will proceed accordingly.

The 500-0047-130 Filter is of 5 Micron

Main filter of 5 micron or 10 micron performs differently in a huge way, as a 5 micron filter prevent most of debris from entering the printer, while a 10 micron one is more welcoming. The 10 micron filters are usually applied on printer with color pigment, which particles are larger than the black ink.

When you look for what micron is of our compatible main filter, please look at the label directly, the number is on there, take the 500-0047-130 Willett main filter for example, we can see 5.0 micron on the label. Some of you may baffled by the numbers printer on the the filter, which is actually our batch number, it has nothing to do with the filtering micron.

If you are not sure which filter should be bought, please feel free to tell us your printer model, ink type etc, we will supply the suitable filters accordingly.

Packing of The Original Liquids

When we purchase the original new ink, solvent or cleaning solution, we expect them to come with an intact original packing. However, the packing must be modified so that we can delivery the liqudis.

Take the Videojet V411-D ink as an example. For starter, we have to remove the “hazardous label” from the cartridge, and then remove the lammable liquid sign from the inner carton. At last, any sign or logo indicating it’s a flammable liquid also have to be scraped.

You may think why go such length to destroy the original packing, the liquids look better with their labels on. Here is why, based on previous liquid delivery experience, courier company may reject the liquids with flammable/hazardous signs on them, apart from that, such labels may cause trouble during customs clearance process. So for both of our own sake, the labels must be gone.
