  • What does it mean by an on-site warranty?

    If your product is registered within 30 days, you will be eligible for the free 3 year on-site warranty. This means that, if you should experience technical difficulties with your printer that cannot be solved over the phone, OKI will arrange a visit from a service engineer or arrange for the product to be returned to them.

  • Does this printer have wireless capability?

    The Oki MC851DN+ does not have wireless connectivity as standard. We do a wireless bundle of the MC851DN+ multifunction printer which makes it wireless https://www.printerland.co.uk/OKI-MC851DN-Wireless-Bundle-P130498.aspx

  • Trevor Moriarty 28 June 2017 1.5 / 5 Value 2 Features 2 Quality 1 Performance 1 Will Never Purchase another OKI Printer

    On performance if I could have put a minus score I would have done. One of the worst bits of kit we have had the misfortune to own.The printer jams on EVERY operation you literally have to sit beside it to get a job done.Less that a year old parts need replacing. Incredibly slow, the customer support from OKI has been appalling and after just over a year of owning it we have given up and will be ditching it for a proper machine......you have been warned.

  • Gillian Stanley 29 July 2016 4.5 / 5 Value 5 Features 4 Quality 4 Performance 5 Setting up

    Really like this laser printer /fax / scanner. I would prefer to have the manual in the box. So can help with set up as I find reading from screen irritating. But what can I say about the service from printer land - excellent ordered after lunch and was deliverd with 24 hours wow great service printer land

  • CLIVE SOPER 10 April 2016 5 / 5 Value 5 Features 5 Quality 5 Performance 5 SURPRISED AND AMAZED

    Having been recommended to us I contacted Printerland to ask for advice purchasing a printer/copier.Luke answered the phone and expertly answered all my questions with confidence and auracy. I placed our order and paid by card having been told by Luke that our new printer would be delivered the next day. 9-30 the following day there was a TNT man at our door delivering our order. I am amazed at the efficiency and quality of service we received with surprisingly efficient and prompt delivery, we will recommend Printerland to anyone. Many thanks from Project Fusion.

  • JJ 31 March 2016 3.75 / 5 Value 4 Features 4 Quality 4 Performance 3 Prints great but slow

    The prints are super but the wait time is very slow. The set up was fairly straight forward ( MAC with connection to router via wif-fi: router to printer ethernet connected) The set-up does not allow you to wi-fi scan. We are using a memory stick at the OKI and then loading manually. Not ideal. Good to know before you buy. If there is someone out there who managed to set up the scanning to be wifi please post here!

  • Jon Ballard 31 March 2016 5 / 5 Value 5 Features 5 Quality 5 Performance 5 Top Machine

    This machine does everything a small business like mine requires. The chaps at Printerland even phoned me before processing the order to confirm I had the right fit for my business. I am very happy with this machine and the service given. I will be visiting them again soon.

  • Emily 23 March 2016 5 / 5 Value 5 Features 5 Quality 5 Performance 5 Big Improvement

    Much better than our old printer. We now have A3 and it also prints a much closer colour to what's on the screen.

  • Chris Hayward 23 March 2016 5 / 5 Value 5 Features 5 Quality 5 Performance 5 Quick delivery great value

    We needed a printer for a small office, we needed A3 as well as A4 so decided on the OKI MC851DN+A3. The sales person was extremely helpful after taking the order he gave me a delivery time slot for the next day. The printer arrived on time with all the instructions for setting up. you have to take out the A4 paper and put in the A3 when you want to print a larger item, but this is easily done. you just need to print all A3 items before changing back to A4. the colour is clear and the printing quick. Well worth the money.

See Exactly Who is Printing What

This optional application for OKI colour, mono and multifunction printers helps to give you a clear overview of of print activity by tracking the output of each individual user or department.

Assign cost values to documents including full colour and duplex (double sided) jobs to allow you to use information gathered to charge back departments or clients.

Easily capture full details surrounding:

  • Colour Vs Black & White pages
  • Number of printed pages

Total Access Control

Keep control over your workgroup's print output by defining who can print and what gets printed. Restrict users to black & white printing or allow access to full colour HD prints.

Assign access levels by username, application, file name, PC/server name or website URL. All policies are password protected and added security is provided by restricting authentication through the system manager.
