If you already own one
The printer you already have is part of this.
Most of the printers we are asked about were bought before the
person asking started the job. They are still running, they are out of warranty, and the
question is never which model to buy. It is one of these three.
“Can I still get a printhead for it?”
Mostly yes — and the honest answer is different for each machine, which is worth
knowing before anybody quotes you.
The industrial lines are well supplied, and they are worth seeing written out, because a
row of names turns out to be one machine growing up. Four inch: the Z4M,
discontinued in March 2004; the Z4M Plus — quicker on a complex label, more
memory, more ZPL II — discontinued in January 2008; then the ZM400, then the
ZT410, and now the ZT411. Six inch runs the same way: the Z6M, then
the ZM600, then the ZT420, and now the ZT421. Printheads for most of
those are current parts, and a 105SL or an S4M likewise. A 170Xi4 is
still obtainable through a Zebra partner; an older 170Xi3 we would have to check
for you.
The Z6M is the one that has genuinely run out. Zebra does not make that printhead
any more, so what you can buy is an OEM printhead rather than a genuine Zebra one.
We will say so before you buy it rather than after — that is the difference between
the right part for an old machine and a part somebody sold you as something it was
not.
What we need is the number off the plate, not the name the office uses for it.
The printheads page lists what we hold and takes the model and
the symptom — a white line down every label is a different answer from faint on one
side.
And if it is faint on one side, try the pressure adjustment before you buy a head at
all. Industrial Zebras have one — one or two toggles on the printhead casting,
or numbered dials on a ZT411, depending on
the model. No tools, nothing to buy, and a scale so you can put it back where it
was. It evens out print that is darker on one side, a ribbon that wrinkles, and a label
that drifts sideways as it prints.
The pressure toggles, and the method for setting
them →
“Can we see the printers without walking out to them?”
Yes, and it is worth knowing if you run more than two or three. SOTI Connect puts
a fleet of printers in one console — firmware and settings pushed without touching
the machine, and the printer reporting its own condition. That includes
printhead temperature and print cycles, which are two of the numbers that
say a head is wearing out before a label does.
It is not Zebra-only either, which matters if your dispatch bay has two brands in it
because of something somebody bought in 2019.
What SOTI Connect does, and whether you need it →
“Is it worth repairing, or do we replace it?”
This is arithmetic, and it is arithmetic we will do out loud rather than guess at. A
printhead plus labour, against the price of a machine that is faster, quieter and still
supported. Sometimes the repair is obviously right — a good industrial printer with
one worn part has years left in it. Sometimes it is not, and the honest answer is that you
are about to spend half the cost of a new one on a printer that will want the other half
next year.
What decides it is rarely the printer. It is how many labels a day it prints, whether
there is a second one beside it when it stops, and what a stopped line costs for an hour.
Service and repairs covers what we do and what it costs, and
a service call can be booked without ringing first.
“What replaces a Stripe, or a Z4M?”
The ZT411 — but not always, and the exception is worth a minute. A
Zebra Stripe from the nineties and a Z4M from the two-thousands were both four-inch
industrial machines built for volumes a modern desktop printer handles without noticing.
Plenty of the work those printers were bought for now runs perfectly well on a
ZD421 at a fraction of the price, because
the volume that justified an industrial machine in 1998 is not what it turned out to
be.
If the volume genuinely is still there, the
ZT411 is the direct descendant, and the
six-inch answer is the ZT421.
Three questions before anybody quotes: how many labels a day, what they are printed onto,
and whether the ribbon and stock you already buy still fit. The last one catches people
— a new printer that wants a different core size quietly changes what every future
carton of labels costs.
“What do we design the labels in?”
Zebra gives you a label program free, and for a lot of people it is the whole
answer. You put the text, the barcode and the logo on, and whoever prints is asked for
the one thing that changes — a date, a part number, a batch. No licence and no
expiry. What it does and where it stops is worth five
minutes before you buy anything.
It stops at the point where the label should fill itself in from a spreadsheet or a
system rather than from somebody typing. That is
BarTender, or Zebra's paid edition, and which one depends on how
many people and how many printers.
