fixed : SPL-C ERROR page printed by Samsung printer

Question :

when I tried to print to my Samsung printer via my Home-network today, the spooling process was very slow, then hung, and then a printed page rolled out of the printer with this text only :

SPL-C ERROR – Disconnected from Host. Please check the connection and try again.

POSITION : 0x3dc5 (252981)

SYSTEM : src_5.59/os_hook

LINE : 1978

VERSION : SPL-C 5.59 05-04-2012

So I restarted the printer, made sure there wasn’t any paper stuck, and tried again. This time I the spooling process was very slow again, hung again, and a similar page rolled out of the printer with this text :

SPL-C ERROR – Disconnected from Host. Please check the connection and try again.

POSITION : 0x15ea5 (89765)

SYSTEM : src_5.59/os_hook

LINE : 1978

VERSION : SPL-C 5.59 05-04-2012

So despite the difference in ‘position’, the problem remained.

What can I do to solve this ?

 

Answer :

This seems to be a weird bug popping up on some Samsung printers connected to Macs once in a while. To solve this problem, do this :

  • quit any printing jobs that are active
  • shut down the printer (take the power cable out)
  • on your Mac, go to System Settings > Printers & Scanners
  • there, delete the problematic printer (by selecting it in the list and clicking the minus-button)
  • then, restart your Mac
  • switch the printer back on (reconnect the power cable)
  • login on your Mac
  • go to System Settings > Printers & Scanners
  • add the printer to the list again (by clicking on the plus-button, and selecting it from the printers found)
  • then close the System Preferences and try printing your document again

That’s it !

fixed : USB-to-Ethernet-adapter not working on Nintendo Switch

Question :

I would prefer to connect our new Nintendo Switch gaming console to the Internet using a cable, as I did with our Nintendo Wii-U. But the USB-to-Ethernet-adapter that was working perfectly on our Wii-U isn’t even recognized by the new Nintendo Switch.

What is wrong ?

 

Answer :

There are 2 sides to this problem, and you might even have to take care of both :

-1-

To use a wired ethernet-connection on the Nintendo Switch, you need to keep the Switch tablet inside the base station. If the tablet isn’t inside the base station, the Switch can’t access the wired ethernet-connection, as there is no wireless connection between the tablet and the base station. Even when docked in the base station, it is the Switch tablet that connects to WiFi directly. There is no WiFi-module inside the base station.

So, follow these steps to get it to work :

  • open the lid on the back of the base station and unplug the power adapter-cable
  • make sure the ethernet-cable is connected to your modem router
  • plug the ethernet-cable into your USB-to-Ethernet-adapter
  • plug the USB-to-Ethernet-adapter into the base station (preferably the USB-port under the lid on the back, as that is a USB3-port)
  • then replug the power adapter-cable into the base station and close the lid
  • then put the Switch tablet into the base station and turn on your TV
  • Go to Settings, then Internet, then Test Connection
  • If the info listed says “Wired Connection” you’re okay and your Internet connection speed will be displayed in a few seconds
  • If not, repeat the above steps and make sure all cables are plugged in properly

-2-

The Nintendo Switch gaming console will only accept USB-to-Ethernet-adapters that are based on the ASIX AX88179 chipset. The only officially supported USB-to-Ethernet-adapter is the Hori NSW-004U Switch LAN Adapter, but any adapter based on the ASIX AX88179 chipset should work perfectly.

buy the officially supported Hori Switch LAN Adapter on Amazon.com here

buy the officially supported Hori Switch LAN Adapter on Amazon.co.uk here

Or you can spare yourself some money by buying one of these (note that these are all USB3, which makes them a cheaper and faster alternative to the Hori-adapter that is only USB2) :

fixed : broken power adapter for Umax SOHO ethernet switch

Question :

I have an old Umax SOHO 1OHO8 ethernet switch that I would like to use in my LAN-network, but the power adapter has a very strange problem : one of the pins that go into the wall power outlet has come loose, and now ‘retracts’ whenever I plug the power outlet.

I already tried gluing the pin back into the power adapter with superglue, but I can’t fasten it, so it keeps coming loose. I also tried using an adapter plug, but I couldn’t find one that enabled me to keep the pin from retracting…

What can I do to fix this ?

 

Answer :

Just buy a new one.

You probably won’t be able to find the original one, but you will be able to find a new generic one with the correct specs.

The specs of the Umax SOHO 1OHO8 power adapter are :

  • AC input 230V (so 100-240V will do)
  • DC output 7.5V 1A (= 1000mA)
  • output plug/pin 5.5×2.1mm (= 5.5mm outside diameter & 2.1mm opening diameter inside)
  • output plug/pin polarity : MINUS outside & PLUS inside

You can get a US-version replacement here : US power adapter 7.5V 1A 5.5×2.1mm

You can get a UK-version replacement here : UK power adapter 7.5V 1A 5.5×2.1mm

You can get a EU-version replacement here : EU power adapter 7.5V 1A 5.5×2.1mm  (note that this one actually has a 5.5×2.5mm plug that is compatible with 5.5×2.1mm)

fixed : use one printer in two networks at the same time

Question :

I have a network printer on my (private) network that I would like to make available to the people on my AirPort Guest Network, but I don’t want guests to access my private network.

Is there a way to do this ?

 

Answer :

There are options to do this, but it can’t be done the way you would find most elegant probably… the problem is the restriction in AirPort Guest Networks that users can’t connect to each other, so adding the printer to the AirPort Guest Network won’t make it available to any AirPort Guest Network user.

On the other hand, an other restriction on most network printers is that they only have one Ethernet-card that is shared between the UTP-cable port and the WiFi connection, so the cable-connection and the WiFi-connection will always have the same IP-address, making it impossible to connect the cable to your private network and joining the Guest Network using the WiFi-connection at the same time…

Your best option is to connect the Ethernet/UTP-cable and/or the printer’s WiFi to your private network and creating a separate network to be used as a Guest Network to which the printer can be connected using it’s USB-cable. Since you will need an extra wireless router or an extra (secondhand) AirPort Base Station or Time Capsule to create this separate Guest Network, you can plug the printer’s USB-cable into that wireless router / AirPort Base Station / Time Capsule.

You could also use a printer server, if it isn’t possible to connect the printer’s USB-cable into the wireless router / AirPort Base Station / Time Capsule. You can find relatively cheap print servers on Amazon.com, Amazon.co.uk or Amazon.de

Regarding the setup of your networks, you will probably be best off doing it like this :

  • set your internet modem in router mode (if you would set it in bridge mode, you wouldn’t be able to connect two separate networks behind it)
  • connect both routers (or AirPort Base Station or Time Capsule) to the internet modem
  • setup one router (or AirPort Base Station or Time Capsule) to create the private network and private WiFi network
  • setup the other router (or AirPort Base Station or Time Capsule) to create the Guest Network and Guest WiFi Network
  • make sure that the IP-ranges issued by both routers are completely different (to prevent easy connection from the Guest Network to your private network (and the other way around)
  • if any of your routers give a “Double NAT” error, just ignore it

That’s it !

the only downsite is that having such a complex network setup with multiple routers will have negative influence on your (internet) connection speed ; this difference in speed will probably not be very big if you have few devices connected, but if you have a lot of devices connected that also use a lot of bandwidth (like video streaming) you will probably have slower internet speed than you used to…

fixed : Time Capsule shuts down almost immediately after startup

Question :

I have a 1st generation Time Capsule that always used to work fine, but recently it shuts down almost only seconds after I turn it on.

How can I solve this ?

 

Answer :

Most of the time, this problem can be solved rather easily.

The cause could be a broken HardDrive inside your Time Capsule (if that’s the case, go here to see instructions on how to replace the HD), but most of the time this specific problem turns out to be an overheated (and therefore broken) power unit.

Even though this type of Time Capsule is marked obsolete by Apple, it will still function in your current WiFi network and can still be configured using the current AirPort Utility app version 6 and newer.

The main problem is probably not going to be to replace the power unit, but finding a new power unit. You might find one on Amazon, but since it will probably be a secondhand item, your will probably have more luck searching for an “A1254 power unit” on eBay, AliExpress or Google Shopping

When you have found a new (secondhand) A1254 power unit, you can build it into your A1254 “1st generation” Time Capsule this way :

  • put the Time Capsule upside-down and use a hairdryer to heat up the rubber base plate and loosen it’s glue (if you don’t do this, you will probably rupture the base plate when you try to take it off)
  • then follow the iFixit manual for replacing the power unit and make sure not to skip the important comment at Step 2 : “The two screws in the top center of this picture should not be removed at this time. They are locating pins on the hard drive.”
  • after taking out the broken power unit and putting in the new (secondhand) power unit in, put your Time Capsule back together doing the iFixit steps in reverse order
  • after plugging the Time Capsule into the power, you can reinstall it into your WiFi network using the AirPort Utility app on your Mac (or on your iPhone/iPad)

That’s it 😉

fixed : upgrade broken HD in old Time Capsule

Question :

My 1st generation Time Capsule always used to work fine, but now the internal HardDisk is broken.

Can I replace the HardDisk easily ?

 

Answer :

Yes you can.

In the ‘old’ flat Time Capsule (like the A1254 “1st generation” Time Capsule), the HardDrive is rather easy to replace. And even though Apple has marked this TimeCapsule ‘obsolete’ it is still able to preform properly and it can be maintained using the current AirPort Utility version 6 and newer.

To do so, follow these steps :

  • get yourself a new HardDisk, preferably a low-energy HD like the Western Digital WD Green 2TB or 3TB (get it on Amazon.com, Amazon.co.uk or Amazon.de) ; these low-energy HDs are especially suited not only because of their low power consumption, but also because of their ability to stay cool during operation since these old TimeCapsules tend to overheat when a regular HD is installed
  • then, place the TimeCapsule upside-down and warm up the rubber bottom plate with a hairdryer to loosen the glue (if you don’t do this, it is nearly impossible to get the rubber bottom plate of without rupturing it)
  • then follow the steps as outlined in this manual by iFixit and be sure to read the important note at Step 2 : “The two screws in the top center of this picture should not be removed at this time. They are locating pins on the hard drive.”
  • then replace the HD and rebuild your TimeCapsule doing the MacFixit steps in revers direction
  • when done, plug your Time Capsule into the power and access it using the AirPort Utility app on your Mac (or iPhone/iPad)
  • in the AirPort Utility app, select the TimeCapsule’s icon and click Edit
  • in the window that opens, go to Disks, then click Erase Disk
  • when that’s done, your new Time Capsule’s HD is ready for use

That’s it 😉

enjoy !
