3]1 printers #dependency@@

 


3-in-1 print/scan[1]/copy is what I need since 2017. My priorities:

  1. low-maintenance .. mostly about outages. Cartridge-replacement is LG2
  2. initial cost .. small amount actually
  3. total consumable cost over a unit’s lifespan (2Y typically)

maintenance ^ TCO trad-off …. For my “occasional printing”, inkjet likely wins on TCO while Laser has a slight edge in terms of maintenance.

Jolt: Once again, the mainstream priorities are unimportant to me, such as print finish, wireless print, even consumable cost

I don’t need any fancy features. I just need basic printing. All features come with headaches [reliability, set-up,,, ]

— feature: outage .. laser beats inkjet, but both types hit outages including scanning.
sleep mode is an outage when I need to access the LCD and power cycle the device ! However, if I can easily see the sleep mode, and easily wake it up, then not an outage.

Printer companies offer _onsite_ repair .. a testimony to the poor MeanTimeBetweenFailure in printers. There are more moving parts in the inkjet model, and more outages.
— feature: consumable replacement t-cost.. (including shopping, refill) laser beats inkjet. A light-duty laser toner can last 1000+ pages before replacement, but (Jolt) a heavy duty inkjet cartridge can last up to 800 pages if not drying up. Some Canon printers can configure for drying.. see below.
— feature: consumable cost… laser beats inkjet. This is LGlp, because I have a low “lifespan” expectation for both inkjet (1->1.5-2Y) and laser models (3-4Y) –> Jolt: As soon as it starts giving problem, I would want to terminate the pain and abandon it. So during the short lifespan, our consumable cost can’t escalate.

A laser toner costs about SGD 40 and can print 1000+

A 300-page Canon cartridge (original) costs SGD30. To reduce cartridge cost, you can get a $7 refill at a Simlim shop. Canon Singapore estimates that for 1080 prints [30 prints/M * 36M] ink consumable costs $100 … inferior to laser consumable. However, there are inkjet models with $0.0018/page. High-end inkjet can rival laser in consumable cost.
… Now I feel the simlim trip to refill is too t-costly. New cartridge can be bought near home.

— feature: initial cost… inkjet beats laser hands down. This cost difference /dwarfs/ the consumable cost difference
! The cheaper, the less baggage.. In 2019, I bought a USD 25 print-only model.

price range .. inkjet is much cheaper than laser in initial cost (also including consumable).
* Laser: [SGD200-300].
* inkjet: [SGD 69 – 100]

— feature: weight and size… inkjet beats Laser.
Lighter models can be moved easily and mounted on a higher shelf. Easier transport for repair
— feature: dry-up .. laser beats inkjet since there’s no worry about “dry-up if 3M no use”.
— [1] Need for scanning .. many people use camera but once a while we still need a “proper” scan of an important document like transcript, certificates.

— new advanges of inkjet over laser

  • energy .. inkjet printer uses (up to) 85% less energy
  • paper jam .. reduction, thanks to lower heat!
  • less bulky therefore easier to fit in.

water-proof? New inkjets are Completely safe, though my low-cost models may not
— $50 HP 2723e details
Android installer download takes a few minutes. The install requires 🙁 🙁 an HP account (Ldn 2011 with one metachar). This printer offers utterly unimportant features [wireless printing, instant ink] that require non-trivial set-up involving wifi capabilities that I don’t have or don’t know.

However, the $50 is a bargain price for the basic functionalities (I ignore those fancy features), so no complaints.

Wireless printing might be useful to wife. Need to confirm with her. Newer printers may have this feature too. Next buy can include this optional requirement.

~ Canon Pixma printer cartridge replace
🙂 no computer required, but stay powered
open the front cover. See youtube.
cartridge would automatically move to the middle for your access.

— Printer driver install
After driver installation, sooner or later, we need an initial connection between the hardware. A common juncture of failure.

If cable is loose or printer is off, then you can check using device-manager — unplugging/turning-off will remove an item immediately from device-manager; plugging/turning-on will add an item immediately to device-manager. Windows may also beep 🙂 These are good signs. If you don’t see any of these signs, then driver is broken or windows is broken.

Note Device manager is more low-level than Printers-n-scanners-page. It is able to show the new device earlier than PnSP can. Windows restart may be required before PnSP shows the new device.

Insufficient diskspace can mess up the installation in some strange way.

I prefer test-printing a single dot (notepad file).

==== 2-printer low cost set-up is one of the top 20 lifestyle improvements since 2020, but ..
Q1: will it be _needed_ in the long run? Probably for a few years
A: I choose to focus on the next few months

Q2: is it lifestyle creep?
A: depends on total cost [the dollar amount + the furniture support]. I think it’s worthwhile

Q3: is it unhealthy dependency?
A: also depends on “availability”. When I can’t have these printers, I will cope fine.

2-printer set-up proved to be surprisingly cost-effective and worthwhile, even though it entails lots of shelf space, wiring, power socket..

— j4: reflective writing.. 2-printer is useful for reflective writing.
When it’s available, I tend to print out, annotate, update online, then print out again.
Reflective writing is part of my wellness-driven life.
— j4: standing .. 2-printer also helps me stand more.

##[24]ext mem #laptop++

Some models are designed for phones and cameras. They are concealed and can’t use USB ports. They are slower.

— For laptops, you can consider all types, if you have the required ports

Fastest .. USB-C and some USB-A devices, up to 400MB for reading. Standard SSD offers 500MB.

SD cards (concealed) .. require card readers. Speed is up to 200MB for reading, unaffected by SD card adapters.

SD cards can be a suitable choice if you want to keep your ext storage permanently attached. However, SSD offers better reliability and longevity for day-to-day storage in computers compared to SD cards.

Warning: installing software in these ext storage devices … may fail, although portable USB-installers should work.

— Device cost … depends on read/write speed, stick-out and GB. For 64GB (becoming smallest), typically $10+, very affordable.

Price tends to drop over the decades, as smaller, slower models phase out.

 

Samsung TV: stressors #wiring,wifi,speaker,,

This new addition in my home creates many changes, and decisions, mostly unwelcome:(. Therefore, it was important to get me and everyone else involved in choosing the model … Buy-in. Also important to slow down in the due diligence.

Too many small and big decisions. Take up a lot of Sys2 bandwidth.

The stress is proportional to the price tag.

My ongoing diet regime is adding a lot of stress.

— external speaker ..
Destressor SMS: No such thing in base camp. So if this doesn’t work we should remind ourselves of base camp.

— wifi ..
Destressor SMS: No such thing in base camp. So if this doesn’t work we should remind ourselves of base camp.

Destressor: We don’t want the TV to have a hard dependency on home wifi.

— mounting rack .. can shift horizontally. Need to be careful.
— lock down the tigerfang5 …
Destressor: good to postpone it, and live with the imperfect set-up.

— other stressors / frustrations

  • worry about remote control misplacement
  • menu navigation [user interface navigation] over complicated
  • messy wiring .. I spent an hour
  • mounted too close to wall. Hard to operate the backside. Needs adjusting on my part.
  • safe keeping of paperwork
  • save the small parts

AC adapter: voltage mismatch

Oftentimes we can’t find the original AC adapter and must use 3rd-party adapters.

https://www.groovypost.com/howto/choose-right-power-adapter-charger-phone-laptop/ describes “voltage too high/low” and “current too low”

==== based on https://www.cdw.com/content/cdw/en/articles/hardware/how-to-choose-the-right-ac-adapter-for-your-device.html

Choosing an adapter with a higher or lower voltage may cause the connected device to malfunction. This happens if the adapter’s VDC is lower than the device’s input voltage even when their current ratings are the same.

Using an adapter with a higher voltage will cause the connected device to detect an overvoltage. An AC adapter supplying electricity at a higher voltage than required will cause the connected device to run hotter. Sending power at a higher voltage will also shorten the lifespan of the device and may fry its internal circuits.

–Using an AC adapter with a lower current rating can be an issue. When considering how to choose an AC adapter, avoid picking one that delivers a lower current than required by the device. Even when both the adapter and the device have the same voltage rating, the device will attempt to draw more current than the AC adapter can manage. This can cause the adapter to overheat. The device may fail to power on or struggle to stay on. If the current is too low, the electronic device may stay on, but its battery will not charge.

It may surprise you that you can use adapters with higher current ratings than your devices. This recommendation holds true, as long as both devices have the same voltage rating. For example, a 10V/8A adapter can safely power a 10V/5A device.

batt overcharge #bloat

For a growing number of devices, there’s a call to avoid overcharging. Ranked by importance/value:

  1. touchscreen laptops .. let’s disconnect once a week to a month
    • default plan .. connected
  2. LED clamp lamp.. Let’s charge when it dims, and disconnect at least one a month.
    • default is either connected or disconnected.
  3. iPhone .. I confirmed with Apple. No worries. It’s more important to avoid low battery when on the move
    • default is connected.
  4. other smartphones .. avoid charging beyond 80%

General advice says

  • for prolonged periods of disuse …
  • for everyday usage, laptops are designed for continuous charge. Modern smartphones, too, to a lesser extent.

If it is important to constantly remember “disconnect !”, if it is as important as my pills or taking my phone when leaving home then it becomes a burden on System2.

Q: can we get used to the burden?
A: yes we can and we had better, iff “important “. This is a non-trivial lifestyle change.

— smartphone batt .. I was told that overnight charge is safe unless battery is already bloated.

As soon we see a bloated battery, we should replace it asap. It may give smoke any time. (It can also damage the phone but I’m less concerned.)

Wisdom — When screen is broken, repair is often not worthwhile, but when battery is old, replacement is often worthwhile, quick and clean.

Vivo 1820 needs special care … its battery is hard to replace. Let’s avoid charging beyond 80%

— Tanko on shoe care .. I’m naturally careful with system test, exams, cCost, tCost, burn-rate … and I am willing to take on the “burdens” of care.

Some people are naturally careful with shoe care. Tanko is the first to remind me the need to take care of costly personal items such as shoes. In contrast, I’m more used to the cheaper, replaceable versions such as (pre-owned) laptops/phones, shoes, dress, backpack
