      The cartridge arrived the next day as promised but sadly proved faulty. However, after a phone call to a very helpful employee, a replacement cartridge was despatched, arriving within 24 hours as promised. Speedy delivery, easy installation, good print quality, sensible price with no postal charges all make Cartridge Save an excellent company. The printer in question is an elderly HP Deskjet 810C - and Cartridge Save compatible High Capacity Black cartridges are ideal and extremely good value.

      3-year warranty on our own-brand cartridges
      We are proud of our own-brand cartridges, so we’ve made trying them a no-brainer. If within three years of purchase you have any problem whatsoever, we’ll happily offer either a replacement or a refund.
      Returning items is easy—it takes just a few minutes. But our return rate is very low, so you’ll be unlikely to need it.
      We are confident that no other own-brand cartridges are better than ours. They produce vibrant prints with accurate colour densities and dark blacks—and their page yields are as good as the genuines, if not better. Give them a try, and see why our customers love them.
      Our own-brand cartridges are incredibly reliable for three reasons:
      1. We are the UK’s biggest seller of own-brand cartridges, and we have invested a lot in optimising them.
      2. We are dedicated to quality. Every own-brand cartridge is performance-tested before it leaves the factory.
      3. We constantly monitor customer feedback, and quickly resolve any issues.

      “In the unlikely event that Cartridge Save own brand cartridges cause damage to your printer—regardless of how old your printer is—we will repair or replace your printer for free.”
      And they won’t invalidate your printer manufacturer’s warranty...
      If your printer is less than one year old, your manufacturer’s warranty won’t be affected by using our cartridges (this is the law). However, in the unlikely event that our own brand products are to blame, we will take over the manufacturer’s warranty offering phone support and, if needed, repair or replace your printer.

      This means there is absolutely no risk in giving Cartridge Save own brand cartridges a try.

      By June Adam on

      I find this a very good service as it is difficult to find shops stocking HP15/HP17 I use them for Hewlett Packard Deckjet 840C. They are quite expensive but last a long time. The delivery is quick and reliable.I would recommend the service.
    2. 100%

      By Sue on

      Arrived quickly, all as promised and printed great immediately. Therefore so far so good and also definitely much better than any 'compatible' cartridges I've bought previously from another company.

      As always, good products and good service.

      good quality product which you would expect from a genuine cartridge. good saving by buying a multipack as against buying black and colour cartridges seperately.

      By Scott Elliot on

      I am just pleased to be able to still obtain ink cartridges for my ageing HP Deskjet 840C and have always used Cartridge Save since the cartridges disappeared from the retail shops many years ago. I use the re-furbished ones and connot tell the difference in print quality between them and the HP originals- even on photographic prints. But a massive difference in price!
      Installation into the HP deskjet 840C is a doddle and I already recommend Cartridge Safe to others.

      I am still using a HP 845C (real oldie that I regularly service myself). These cartridges are excellent value for the price. They are simple to install and produce very good print quality. Not forgetting the unbeatable delivery speed.

      By J McG on

      This would have a higher rating but the first cartridge ordered was faulty - it did not print red. I had been wanting to print something fairly urgently, so was annoyed at having to delay.
      However, I phoned and was sent a replacement, which arrived the next day, and has been fine. The service from Cartridge Save has been efficient on the three occasions I have used them.

HP Deskjet 840c Printer Review

Expert review of the HP Deskjet 840c printer

Our Verdict:

The HP Deskjet 840C is specifically designed to meet the demands for a reliable, user-friendly, and speedy colour inkjet printer. The Hewlett Packard 840C printer produces photo-quality images and laser-sharp text because of the technologies that HP integrated into the device, and versatile paper handling options allow users to be creative with their print jobs for work or for personal use. Unfortunately, the Deskjet 840C inkjet printer is quite old, so its claimed 'superb performance' may be sub-par according to today's standards.

Design

Integrated with HP technologies like colour layering and coloursmart, the HP Deskjet 840C colour inkjet printer aims to print pictures and documents flawlessly for professional needs. The HP 840C is USB and parallel compatible and uses drop-on-demand thermal inkjet printing method, plus HP PCL level 3 printer language. The Deskjet 840C printer runs on 2MB of RAM with a 48kb receiver buffer and weighs 5.5kg without the pens and power supply.

Advantages

The HP Deskjet 840C is compatible with USB connections for plug-and-play convenience. It prints images according to how they appear on the monitor, and photo-quality graphics are possible regardless of the media used because of HP Colour Layering technology. Black texts look sharp and laser-like for professional-looking documents. The HP Deskjet 840C inkjet printer can accommodate different types of speciality paper, so users can use it for their greeting cards, banners, labels, and transparencies.

Disadvantages

Print speed for black text is only 8ppm in draft mode while print speed for full-page colour graphics is sluggish at 0.2ppm in best mode. The highest resolution of the HP 840C Deskjet printer is 600x600dpi, which is quite low when compared to printers by other brands. Operating system compatibility is very limited to older versions of Windows (before Windows XP). Mac systems need a USB connection to sync with the HP Deskjet 840C colour printer.
